Docker has revolutionized the way developers build, ship, and run applications. Whether you're a beginner or an experienced developer, mastering these essential Docker commands and tips will make you more efficient and productive. Before using Docker, ensure you have it installed by running: docker --version To get detailed system info, use: docker info Quickly run a container with: docker run -d -p 8080:80 --name my-container nginx This runs an Nginx server in detached mode (-d), mapping port 8080 on your machine to port 80 inside the container. To see all running containers: docker ps To include stopped containers: docker ps -a Stop a running container: docker stop my-container Remove a stopped container: docker rm my-container Remove all stopped containers at once: docker rm $(docker ps -aq) Over time, unused images take up space. Remove them with: docker image prune -a If you have a Dockerfile, build an image with: docker build -t my-app . This tags the image as my-app. Use interactive mode to execute commands inside a running container: docker exec -it my-container /bin/sh For Ubuntu-based containers, use /bin/bash. Monitor logs with: docker logs -f my-container The -f flag shows real-time updates. Copy files from your local machine to a running container: docker cp myfile.txt my-container:/app/ Copy files from a container to your machine: docker cp my-container:/app/myfile.txt . Instead of running multiple containers manually, define them in docker-compose.yml and start them with: docker-compose up -d Stop and remove all services: docker-compose down 💼 LinkedIn | 📂 GitHub | ✍️ Dev.to | 🌐 Hashnode Found this useful?

When working with query parameters in your React app, especially in tools like filters, pagination, or search inputs, you often want to persist those query parameters as users navigate across different views. In this post, you'll learn how to build a simple and reusable custom React hook using react-router-dom that preserves query parameters during route changes. Imagine you're on a URL like: /products?category=books&page=2 Now you click on a product to go to its detail page: navigate('/products/123') 💥 Boom! You lose your query params. When the user clicks the back button, they're dropped on /products instead of where they left off (/products?category=books&page=2). Let’s fix that by creating a useNavigateWithQuery hook. This hook wraps React Router’s useNavigate and useLocation to pr…  ( 4 min )

1. Introduction "Ever scrolled through a modern dashboard and thought, ‘Damn! This feels so fluid… how do they do that?’" If you're a frontend developer in 2025, chances are you’ve asked yourself this at least once. Animations have quietly become one of the most influential parts of the user experience. They’re no longer just about making things "look cool"—they guide the user, provide feedback, and elevate interaction into engagement. In the early 2010s, animations were mostly afterthoughts—extra polish added at the end of a project if there was time. Today, they are baked into the design process from Day 1. With products competing for attention in milliseconds, smooth transitions, responsive feedback, and motion-based storytelling are the new UX fundamentals. But here's the catch—not a…  ( 8 min )

Originally published at Perl Weekly 721 Hi Two weeks ago I asked How do you deal with the decline in Perl-related jobs? and I received quite a few nice comments. Thank you! I'll have another question today. Yesterday I asked in a Web 3 group how to get started with Web3, Blockchain, cryptocurrency, Ethereum.... I got a few suggestions including a link to the Blockchain Roadmap. So I checked. There is also a Python Roadmap and a Rust roadmap, but I have not found a Perl Roadmap. Not even a community created one. IMHO, if you are interested in making Perl easier to learn, more available and hopefully more popular than you might want to invest some time to create a community roadmap for Perl and maybe even to get it listed as an official roadmap.

I originally posted this post on my blog a long time ago in a galaxy far, far away. Last year, I sent out over a dozen of CVs and cold emails within a month. I was laid off. I went into panic mode. I applied to many companies. Anything with the word "coding" or "software engineering" in the job description. I even applied to a FAANG though I rejected that idea years ago. But I just got radio silence. I know because I wasn't the only one going through layoffs. The entire industry was. I even talked to an ex-coworker and he told me he had sent one hundred applications. I don't know if he meant literally 100 applications or not. But I wouldn't be surprised. He only got two or three positive responses.

Type Inference TypeScript can often guess types automatically. This is called type inference. When you assign a value without an explicit type, TypeScript infers it. For example: let count = 10; // inferred as number let message = "Hello"; // inferred as string The compiler knows count is a number and message is a string from these initial values. Type inference helps keep code concise and still type-safe. You don't always need to write : number or : string because TypeScript figures it out. Less code: You skip repetitive type annotations. Safety: Even with fewer annotations, TypeScript checks types. Readability: Code stays clean while avoiding obvious errors. However, you can still add type annotations if it makes the code clearer or if a variable’s type isn’t obvious. …  ( 6 min )

What is Mobile First Design? In practice, this means designing for the smallest screen sizes first, ensuring that essential content and functionalities are accessible and user-friendly on mobile devices.

Designing with mobile users in mind ensures that the majority of your audience has a seamless experience. 2.Performance Optimization Mobile devices often have limited processing power and slower internet connections compared to desktops.

I've always liked the idea of running my own projects, websites, scripts, maybe even some AI experiments. Naturally, I started with AWS since I was already familiar with it. But very quickly, I ran into a wall: COST. 🧠 The Plan: Keep It Cheap, Keep It Useful 🖥️ What I Bought What I didn't check: Rookie mistake, but nothing I couldn't fix. 🔧 The Setup Total cost: ~$150 for a fully working server. 🔐 Security - Why I'm Still Okay With This None of them require external access from strangers or handle sensitive data. So while this setup isn't Fort Knox, for local, low-risk projects, it works just fine. ⚙️ What It's Running Now Now I don't have to worry about draining my laptop battery or shutting off scripts accidentally. And no AWS bills. 🤕 What Went Wrong (But I'm Glad It Did) But those…  ( 5 min )

A recent proposal that aims to change Bitcoin’s base unit to make it easier to understand as a payment tool has run into opposition, with critics saying Bitcoin’s satoshis are no more confusing than the dollar’s cents. Bitcoin developer John Carvalho introduced Bitcoin Improvement Proposal-177 on April 23, which seeks to eliminate the concept of satoshis, of which there are 100,000,000 in 1 Bitcoin (BTC), and effectively split Bitcoin’s fixed supply of 21 million into 21 quadrillion units. It follows a 2017 proposal from Bitcoin developer Jimmy Song to create “bits,” representing one-millionth of 1 Bitcoin. However, Carvalho said Song’s approach would still require Bitcoin users to think about decimals and “shifts complexity rather than eliminating it.” Block Inc. CEO Jack Dorsey is among…

EPS vs PNG: What’s the Difference? EPS (Encapsulated PostScript) is a vector file format used mainly for print workflows and high-quality graphics. It retains shape, curve, and scaling data—great for logos and illustrations. PNG (Portable Network Graphics) is a raster format ideal for digital content. It supports transparency and lossless compression, making it perfect for websites, apps, and UIs. So why convert? Because: Browsers don’t support EPS natively PNG is lighter and easier to preview You might need thumbnails or web-friendly versions of design assets Python makes this easy using the wand library (a wrapper for ImageMagick): bash with Image(filename='logo.eps', resolution=300) as img: ImageMagick is a powerful command-line tool that supports EPS to PNG conversion out of the box: bash bash If you're building a web app or serverless function and don’t want to install heavy dependencies, consider these APIs: Cloudinary: Offers format transformation pipelines CloudConvert: Easy-to-use REST API ConvertAPI: Handles over 200 file types including EPS Here’s a sample request using CloudConvert: bash https://api.cloudconvert.com/v2/jobs \ Web apps that allow users to upload and preview logos or designs Automated pipelines for asset generation or optimization CMS tools that generate thumbnails or social previews from design files Whether you're writing a backend service or automating a design workflow, converting EPS to PNG is a straightforward but essential task. For local scripts, go with Python or ImageMagick. For cloud scalability, plug into an API. Got a preferred method or tip for EPS to PNG? Drop it in the comments or share it on GitHub.  ( 4 min )

Automation promises simplicity—tasks repeated flawlessly, outcomes consistently predictable, and infrastructure harmoniously stable. At the heart of these captivating promises lies idempotency , an elegant idea proclaiming that no matter how many times we run an operation, the result remains steadfastly unchanged. Yet, the shimmering promise of automation's reliability seldom matches reality. In the messy arenas of operational infrastructure, idempotency frequently escapes our grasp. Like a distant horizon, it coaxes and compels—but rarely feels fully attained. Why does the concept of reliable idempotency struggle when translated from whiteboards to production realities? The culprit is the capricious, ever-changing landscape of real-world infrastructure management. Consider a familiar scen…  ( 6 min )

"I didn’t know how anything would work when I started—just had a vague sense I’d figure it out along the way." I wanted to understand how computers really work—beyond just writing high-level code. I needed to deepen my knowledge and prove to myself that these low-level systems aren’t inherently difficult; you just need the right concepts. So, I decided to build a MIPS emulator. I broke it down into three parts: Loading the binary code from a MIPS program Decoding the binary instructions Executing them At first, I didn’t even know how to load a file, let alone parse instructions. So that’s where I began. We need a binary file that contains MIPS instructions in raw binary format. There are other formats like ELF, but I chose to keep it simple with a .bin file.

Introduction: The BPM Paradox Business Process Management (BPM) is designed to improve efficiency, streamline operations, and boost performance.

They believe they’re becoming more efficient… when in fact, they’re silently slowing themselves down. What if your BPM system—designed to drive performance—is actually blocking innovation and costing you time?

It involves defining every step in a process (e.g., invoice approvals, onboarding, leave requests), and turning th…  ( 5 min )

Back then, there was just digital marketing. Then product marketing. We’d segment audiences, figure out what they need, fear, and want. We’d find where our product fits, then build campaigns to fish. Developer marketing isn’t so different. Except, once you identify this audience, you don’t fish. You sit with them. You learn their pain points. You plug into their workflow. You speak their language. And you earn the one thing that moves the needle: trust. I’ve written a lot about developer marketing. Most of it lives on The New Stack and Hackmamba.

In this article, we explore the technical details of how this CLI empowers professionals to deploy, manage, and monitor MCP deployments efficiently. The Contextum CLI (ctxctl) is a command-line tool designed to interact with the MCP stack. It provides fine-grained control over deployment lifecycle operations including cluster initialization, node provisioning, configuration updates, monitoring, and teardown. The CLI abstracts low-level orchestration complexity. Under the hood, it wraps tools like Terraform and Ansible (or native equivalents) to provision infrastructure and bootstrap MCP nodes across global regions. ctxctl init --name dev-cluster --region us-east --nodes 3 ctxctl deploy --config config.yaml …  ( 4 min )

Recentemente eu desenvolvi o desafio da Woovi com Koa.js e GraphQL (link do projeto). Uma das especificações opcionais era o uso do graphql-http, substituto do koa-graphql, que está presente no playground disponibilizado. No entanto, me deparei com alguns problemas iniciais: diversas funcionalidades não estavam presentes no graphql-http, visto que ele é apenas uma implementação do GraphQL sobre HTTP, isto é, é simples e minimalista. Primeiro, por quê? Bom, principalmente, porque koa-graphql foi praticamente descontinuado e graphql-http deve ser utilizado ao invés disso. Tomei esta decisão baseada em uma discussão que inclusive recomendava o uso do yoga, uma alternativa mais completa para servidores graphql, no entanto, eu vi que seria completamente capaz de resolver apenas com graphql-htt…  ( 5 min )

This week’s post is mainly based on the Hashmap project and is just a brief summary of the project as I did not keep very detailed records, due to many setbacks I had for numerous reasons. I completed the Hashmap project I realised that I hadn’t used node.js to do the Linked List project (and I should have), so for this project, I did not use an index.html and ran my file using node.js from within Visual Studio Code. In order to do this, I had to use VSC debugger and I had to admit that I found it tricky at first. Sometimes nothing happened when I stepped through the code, sometimes nothing got displayed to the console, but I persisted with it and managed to figure out enough to be able to debug and create a working program. I had a lot of problems using the ‘this’ keyword, which intr…  ( 4 min )

We often treat threat modeling and test planning as two separate disciplines. One belongs to the security team and lives in architecture diagrams. The other belongs to QA and rides shotgun with feature delivery. But in a world where security flaws are more business-critical than ever, this division doesn’t make much sense anymore. What if we stopped treating threat modeling as a theoretical security ritual and started using it as a blueprint for our test plans? What if the same mindset that helps identify potential attack vectors could also guide what we validate, automate, and protect in our test suites? Turns out, it can. Let’s be honest—most development workflows treat security as a checkpoint, not a mindset. You’ll hear “we’ve completed the threat model” during early planning. But week…  ( 5 min )

Originally published on Medium. Motivation is great — when it shows up. But consistency builds skills, habits, and portfolios. Some days I wake up inspired to build something new. Other days, I don't even want to open my code editor. If I waited for motivation to show up, I'd still be stuck at day one. Motivation is emotional. It depends on sleep, mood, weather, food, dopamine, whatever. It’s not stable. And that’s fine — we’re human. But if we rely on it to work, we’ll work very little. I’ve lost count of how many times I told myself: “I’ll do it tomorrow when I feel more ready.” That tomorrow rarely came. Consistency doesn’t rely on feelings. It’s a system. A rhythm. A muscle. One commit a day One blog post a day One small bug fix Even when it’s not perfect, or exciting, or ideal — it adds up. I stopped overthinking I built projects faster I became more confident I got better — not in a dramatic way, but quietly, steadily Even this blog you’re reading — it exists because I chose to write daily, not when I “felt inspired.” “Write for 15 minutes.” “Fix one component.” Something so small, it feels easy to do — and hard to skip. I don’t care if today’s task is small or ugly. I care that I showed up and made a move. When it comes, I enjoy it. When it’s gone, I work anyway. Motivation is a great bonus. But consistency is what builds portfolios, opens doors, and turns beginners into professionals. Don’t wait for the right moment. Build the rhythm that brings progress — no matter how you feel. Do you rely on motivation, or do you have a system that keeps you moving?

what happens when the biggest liability becomes your greatest asset Introduction: Every dev team has that one engineer. You know the one. The code commit comes in and suddenly half of staging is on fire. They push on main, forget semicolons, and somehow manage to brick a Docker container by renaming a folder. At first, we laughed. Then we cried. Then we made rules like “Nobody touches deploy unless it’s Monday–Wednesday, 9 to 5, and you’ve had coffee.” This person, let’s call him Dave, wasn’t just junior. Dave was entropy in human form. If there was a weak spot in the system, Dave would find it not on purpose, just as a side effect of existing. We called him the worst programmer on the team.

The job description promised creativity, deep focus, and the thrill of building great products. Instead, you wake up to 89 Slack notifications, a failing CI pipeline, and a calendar stuffed with meetings labeled “Quick Sync” that last 45 minutes and accomplish nothing.

Hey there, fellow developer! 👋 Let's talk about something that sounds intimidating but doesn’t have to be: managing CI/CD for monorepos. Imagine your codebase as a bustling city—each project is a neighborhood, and CI/CD is the public transit system keeping everything running smoothly. But when one road closes, you don’t shut down the whole city, right? Let’s explore how to keep your monorepo efficient, scalable, and sane. Why Monorepos? (And Why CI/CD Gets Tricky 🧩) Monorepos are like a shared workspace for your projects: Pros: Unified dependencies, cross-project refactors, and streamlined collaboration. Cons: A single commit can trigger chaos if CI/CD isn’t optimized. The Challenge: Over-testing: Rebuilding everything on every change. Dependency Hell: "Wait, which service u…  ( 4 min )

The In-Memory Advisor in Oracle 23ai analyzes database workloads to estimate DB-Time for various In-Memory sizes. Additionally, it can recommend which objects should be placed in the In-Memory column store. To use this feature, you must leverage the DBMS_INMEMORY_ADVISE package. The procedure for running the In-Memory Advisor is similar to the Privilege Analysis feature. To generate advice regarding In-Memory optimization, you first need to start a task and let it analyze the database workload. Once sufficient analysis has been performed, you can stop the task and review the generated report. The following sections detail the steps to generate the report: Step 1: Enable Heat Map SQL> exec dbms_inmemory_advise.start_tracking(:task_id); ORA-20000: Heat map is not enabled.

🧠 Introduction As blockchain scalability becomes increasingly important, Layer 2 solutions are gaining momentum. Among them, StarkNet stands out due to its use of zero-knowledge proofs (ZK-STARKs) to enable scalable and secure computations. However, StarkNet development involves a unique stack — from Cairo smart contracts to frontend integration via StarkNet.js. In this article, you'll learn how to: Write a Cairo 1.0 smart contract with access control. Deploy it on the StarkNet testnet. Build a frontend using React. Connect it to wallets like Argent X or Braavos. Interact with the contract using StarkNet.js. Let’s start with a simple secure counter contract. Only the contract owner can increment the counter, while anyone can view it. #[starknet::interface] trait ICounterContract<TContra…  ( 5 min )

Hi, I’m Mridul Bansal. I’m 18. A first-year student at Newton School of Technology, Pune — but this isn’t about college. This is about a choice I made a few weeks ago: to become one of the top 100 AI/ML minds on the planet in the next 3 years. And I’m documenting everything. Every hour, every line of code, every mental breakdown, every rebuild. This is Day 1 of that journey. But it didn’t start today. In March, I joined offline coaching for Full Stack + AI/ML because YouTube wasn’t enough for me. I’m someone who learns best when I’m all in — environment, people, mindset. So I customized my learning path: Full Stack (MERN) My mindset shifted fast. From just wanting to stay ahead in college → to dominating my batch → to aiming at global level skill. That’s how I landed here. What I Did This Week This past week was about setting foundations — mentally, technically, and emotionally. My Weekly System (Moving Forward) Execution Stack: React.js + MongoDB coming next _ Posting Plan- _ I won’t be posting every day. I’ll post here once a week — just to keep it real and show exactly what I’ve built or learned. No fluff. Just raw execution logs, week by week. Closing Thought- I’m not doing this blog for likes. I’m writing this so that when someone 2 years from now wants to know how I did it — they won’t just see the success, they’ll see the system. No motivation quotes. No branding tricks. Just one guy documenting his rebuild. Let’s build.  ( 4 min )

As the Head of Engineering at Bacancy, I often speak with businesses that are hesitant about moving to the cloud. They understand the benefits but worry about the complexity. What if the migration disrupts operations? What if costs go out of control? What if the existing infrastructure is too rigid to support the transition? These are valid concerns. But when a company like Bajaj Finance successfully moves its core lending platform to the cloud, it sends a strong message. If they can do it, so can you. This shift was not just a technical upgrade. It was a clear business decision aimed at making their infrastructure more agile, secure, and ready for growth. Bajaj’s move demonstrates that even the most critical systems can run better in the cloud. And they are not alone. We’ve helped several…  ( 6 min )

“We version packages, sign commits, and write changelogs — but our UIs stay anonymous.” That didn’t sit right with me.

The use of yield return in C# has always been a bit of a mystery to me, but recently I’ve come to understand a bit better how it works and when it can be useful. Put simply, yield return allows you to generate values on demand as if they were part of a collection (IEnumerable), without having to manually create or populate a list. Items are returned one by one, only when needed, without storing them all in memory beforehand. Its main advantage lies in supporting lazy evaluation. Imagine you're working on a system that processes data from a large source (maybe a .csv file to be imported or even a .txt log file). In such cases, yield return can optimize memory usage, since it lets you load only one line at a time and begin processing immediately, without waiting to read the entire file. IEnu…  ( 6 min )

User experience design (UX design, UXD, UED, or XD), upon which is the centralized requirements for "User Experience Design Research" (also known as UX Design Research), defines the experience a user would go through when interacting with a company, its services, and its products. User experience design is a user centered design approach because it considers the user's experience when using a product or platform. Research, data analysis, and test results drive design decisions in UX design rather than aesthetic preferences and opinions, for which is known as UX Design Research. Unlike user interface design, which focuses solely on the design of a computer interface, UX design encompasses all aspects of a user's perceived experience with a product or website, such as its usability, usefulness, desirability, brand perception, and overall performance. UX design is also an element of the customer experience (CX), and encompasses all design aspects and design stages that are around a customer's experience.  ( 3 min )

🔙 Previously: Inside the UDP Protocol: Anatomy, Features, and “Non-Services” UDP may be lightweight and “unreliable” by design, but that hasn’t stopped developers from building powerful real-world systems on top of it. In this of the series, we’ll see how two critical technologies — WebRTC and DNS — successfully use UDP and turn its limitations into strengths. What is WebRTC? Why WebRTC uses UDP: But UDP alone isn’t enough — so WebRTC uses helper protocols: ICE (Interactive Connectivity Establishment): Tries multiple network paths and chooses the most efficient one.

Remember the sinking feeling? Not too long ago, while spearheading the development of an e-commerce platform with its heart set on the vibrant markets of East Africa, I slammed headfirst into the wall of payment gateway integration. The global giants — Braintree, PayPal, the names you know — all presented the same frustrating barrier: geographical restrictions that locked out developer configurations from our region. Even Flutterwave, a local contender from Nigeria, often felt like navigating a maze of its own making, riddled with unexpected bottlenecks. Then, a beacon of accessibility emerged: Pesapal. Finally, a gateway that understood our landscape, seamlessly supporting the mobile money, card payments, and bank transfers that power commerce across East Africa.

Do you see anything wrong in below image? 👀 No? 🧐 I have made a minor change do you see what I am talking about now? This is something that tripped me up recently — turns out it’s caused by a little CSS behavior called margin collapsing. 🤔 So, what is Margin Collapsing? As per MDN: The top and bottom margins of blocks are sometimes combined (collapsed) into a single margin whose size is the largest of the individual margins (or just one of them, if they are equal), a behavior known as margin collapsing. Note that the margins of floating and absolutely positioned elements never collapse. In simpler terms: This can make it feel like your margins are “disappearing” — which is exactly what I experienced! 🔧 How to Fix It? .parent { display: flex; /* or grid */ } 🌱 Why This Mattered to Me After some digging, I found this gem of a page: Mastering Margin Collapsing - MDN Highly recommended read if you’ve ever felt CSS was gaslighting you. ✅ TL;DR If vertical margins seem to “disappear”, margin collapsing might be the culprit Happens between block elements’ top/bottom margins Avoid it using display: flex, grid, or some padding Would love to hear if you’ve faced this before — or if this helped you spot a sneaky bug.

“Não é a tecnologia que trava o time é a ausência de uma gestão estruturada.” Nos últimos anos, vi de perto o impacto da má gestão técnica: times extremamente talentosos, com stacks modernas e processos de entrega sofisticados, paralisados por falta de clareza, alinhamento e foco. Foi nesse contexto que percebi como a gestão de projetos deixou de ser apenas uma função organizacional e passou a ser um pilar técnico. A engenharia precisa de autonomia, mas também precisa de direção. Não adianta termos um time que domina o React, o Kubernetes ou o GitHub Copilot se os ciclos são confusos, as prioridades mudam a cada reunião e as entregas perdem consistência.

I have been building a React-based video editing SDK tailored for apps that need to generate, edit, or enhance video content — especially AI-generated content like explainers, reels, and product showcases. As more AI tools pump out video content, one big pain point keeps surfacing: “How do we give users manual control over what the AI just made?” Most AI video tools can generate content — but they fall short when users want to fine-tune it. You get a video, but can’t easily: Add styled captions Adjust scenes Sync audio Edit the timeline Apply effects So I am building a toolkit that lets you embed an editing layer right into your frontend. Here’s a breakdown of what the SDK offers out-of-the-box: Media Utils Extract metadata (video, audio, images) Resize and fit media for different layouts Generate audio visualizers Extract audio from video Media Parser Convert .mov / .webm ➝ .mp4 Compress large video files Handle encoding seamlessly in the background Lambda Integration Export videos via AWS Lambda Save output directly to cloud storage (S3) Timeline Editor Trim, split, and arrange media layers Add & sync text, effects, and audio Timeline-based editing made React-friendly AI-Powered Captions Auto-generate captions from voice/video Apply styled caption themes Live Edit Canvas Drag, resize, rotate video elements Realtime sync with the timeline Live preview as you edit UI Visualizer Panel-based editor Built-in state management (with undo/redo) Effects Engine Canva-style animations: pop, flicker, fade, zoom Text effects: typewriter, staggered, bounce Visual filters for color grading & tone This SDK is ideal for: AI video generation tools (ChatGPT agents, script-to-video platforms) Social media automation apps Product marketing video builders Internal tooling for media teams Watch it in action?

In recent times, with Cursor, lovable, and 101 other AI tools, I see many junior developers jumping on the AI bandwagon and just using generators to scaffold code. I also see a great deal of fear in the industry as well, fear that AI will take our jobs. The standards are becoming tougher, it's no longer enough just to know HTML+CSS and a backend language. To survive in modern times, you need to have a deeper understanding of programming and the tools in general. By attending a BootCamp and learning how to build something in [enter framework here], you most certainly can get a job in a few weeks or months' time. However, if you want to survive in the industry for 10+ years and beyond, you need to equip yourself with skills beyond what the market wants today. You should be able to pivot based on demand and grow as the industry changes. To do this, the best place to start is not the docs of [enter framework here]. Rather, it's computer science. Most of the industry has changed a lot in the past 20 years, but actually, the core concepts haven't changed much; thus, learning computer science will help you develop a strong, deeper understanding of how things work and therefore allow you to become a better problem solver. Having been around the block for more than 15 years, I have worked on many, many different problems of varying complexities. Many of these required me to draw on advanced programming and networking knowledge.

Chances are: No. I’ve been there too—dropping in components and rolling with the default styling, thinking “it looks good enough.” But here’s the truth: ShadCN is not meant to be used as-is. It’s designed to be customized! Let’s break down why most developers skip customization, what ShadCN is doing under the hood, and how you can easily customize it in minutes. There are two main reasons: It works out of the box – so we don’t need to tweak anything. It looks confusing under the hood – global CSS variables, HSL values, Tai…  ( 5 min )

When you hear the word "cookies," you might think of delicious baked treats. However, in the digital world, cookies play a crucial role in enhancing your online experience. Let's Understand what cookies are, how they work, and why they are important. In the context of the internet, cookies are small pieces of data stored on your device by websites you visit. They are designed to hold a modest amount of data specific to a particular client and website and can be accessed either by the web server or the client computer. This allows the server to deliver a page tailored to a particular user, or the page itself can contain some script which is aware of the data in the cookie and so is able to carry information from one visit to the website (or related site) to the next. When you visit a websit…  ( 5 min )

By Dhanian (@e_opore) Coding is more than just typing lines into an editor—it’s a craft, a puzzle, and for many of us, a deeply personal journey. Over time, I’ve danced between two wildly different approaches: normal coding—disciplined, logical, structured—and vibe coding—fluid, music-fueled, and sometimes beautifully chaotic. Both have shaped me as a developer. One grounds me, the other frees me. Today, I’m sharing their magic, quirks, and how you can find your rhythm between the two. Plus, I’ll introduce a resource I built to help you level up your style—available now on Gumroad. Normal Coding: The Architect’s Path Normal coding is like building a skyscraper with blueprints and permits in hand. It’s deliberate, precise, and designed to scale. When I started coding, this was my comfort …  ( 5 min )

Quality Assurance (Garantia da Qualidade) é um conjunto de práticas e processos voltados à garantia da qualidade de um produto ou serviço durante todo o seu ciclo de desenvolvimento. No contexto de software, refere-se ao trabalho desempenhado por profissionais ou equipes especializadas cuja principal responsabilidade é assegurar que o produto final atenda aos padrões de qualidade estabelecidos, seja confiável e esteja em conformidade com os requisitos funcionais e não funcionais. O teste de QA é uma etapa fundamental do processo de desenvolvimento de software. Trata-se de uma avaliação sistemática e contínua cujo objetivo é verificar se o sistema atende aos requisitos definidos, identificando falhas, inconsistências ou comportamentos indesejados. Esses testes podem ser realizados em difere…  ( 5 min )

In economics, Gresham's Law teaches us that "bad money drives out good." A powerful analogy, and surprisingly pertinent, permeates the daily life of software engineering: low-quality code tends to supplant well-crafted code. In a software development ecosystem often pressured by tight deadlines and continuous deliveries, the temptation to opt for quick and superficial solutions ("bad code") can become overwhelming. Although these approaches may offer short-term gains, they insidiously undermine the health and sustainability of our projects. The Mechanisms of Degradation: The "driving out" of good code by bad code is not a sudden event, but a gradual process driven by several factors: The Shortcut of Immediate Implementation: Under pressure, creating low-quality code, focused on the immed…  ( 5 min )

Read the full story here → What 117 Days of Reflection Taught Me About Crafting Code That Endures For 117 days, I've been writing a short reflection every morning. At first, it was just a quiet ritual. A way to center myself before diving into code. But over time, it became something else. I started noticing patterns in how I approached problems, how I rushed when I should have paused, and how often I worked around I should have worked through it. These reflections reminded me of the kind of developer I want to be. One who builds with care and writes code that stays strong when things get messy. Here are a few lessons that stuck: Each day, I pair a short insight with a quote from the Stoics. Not to sound wise, but to stay grounded. I'm sharing them here if you ever want to slow down for a minute: Daily Developer Reflections There's no secret to better code. Thanks for reading. If any of these ideas resonate with you, I'd love to hear what you've learned from your daily practices.  ( 3 min )

Analyzing the performance of a full-stack application (Java and Angular) running on Amazon EKS requires a combined approach, as async-profiler is primarily focused on the Java backend. Async-Profiler is a low-overhead sampling profiler for Java applications running on the HotSpot JVM. For the Angular frontend, you’ll primarily rely on browser developer tools and potentially some Angular-specific profiling techniques. Container startup performance presents a significant challenge for Java-angular applications running on Kubernetes, particularly during scaling events and recovery scenarios. Performance profiling in containerized Java applications has long presented significant challenges. Async-profiler, a lightweight sampling solution that offers an interesting approach for Java workloads r…  ( 4 min )

Rajesh was a senior developer. Ten years in the game. bad Developer Experience feels like. Think of DevEx—short for Developer Experience—as the user experience for developers. The speed of CI/CD pipelines The clarity of your internal docs The quality of your API responses How friendly your error messages are The way your tools support (or frustrate) your flow And here’s the kicker. You can build it like a product. Let’s be honest. A complex codebase A barely working staging server Outdated Confluence pages Random Slack threads with tribal knowledge Then say, "You good?"

🏹 Null Safety in Kotlin Dodging the Null Pointer Exception, the Kotlin way🤓🤓 ➤ Concept of Strict Null Safety in Kotlin • Safe Call Operator ( ?. ) in Kotlin ( ?: ) in Kotlin ( !! ) in Kotlin. Kotlin allows to store “Null” values in a variable. In Kotlin, the variables can be made of Null types by just adding a “?” symbol to the right side of the data type. A nullable type variable means it can also hold “Null” as a value in it. A non-nullable type variable means that it can not hold “Null” as a value in it. The safe call operator is simply a question mark followed by a dot ( ?. ) The safe call operator in Kotlin, is one of the methods to impose “Null Safety Checks” on the nullable variables. If the left-hand side of the operator is null, then it will return null value. If the left-hand side of the operator is not null, then it will return the result of the right-hand side expression. The elvis operator is represented by a question mark followed by a colon ( ?: ) The elvis operator in Kotlin, is one of the methods to impose “Null Safety Checks” on the nullable variables. If the first operand is not null, then this operand will be returned by the elvis operator. If the first operand is null, then second operand will be returned by the elvis operator. The Not Null Assertion is represented by a double exclamation mark (!!) The Not Null Assertion in Kotlin, is another tool to deal with nullity. This operator explicitly casts nullable variables to non-nullable variables.  ( 3 min )

"The main motivation, the original motivation for (creating) Lean was in software verification, right? I mean, Z3 was very popular at bug finding, for bug finding at Microsoft, was very influential there. But (for) Lean the goal was, can we make the same, have the same success of software verification? We went to a very strange path. I mean, having impact in mathematics that we never dreamt of. But the goal in both cases is like we, both in software mathematics and in AI, today rely on manual review, partial testing. A mistake in a theorem can be catastrophic, invalidating the whole result. The same thing (happens) for a critical piece of software, right? And one thing I see all the time, people fearing to make a change a piece of software because they fear by making the change they may be introducing a bug, especially if it's a critical piece of software."

Exploring the bugs, bloat, and burnout behind today’s software and why it’s not entirely your fault. Introduction: welcome to the software multiverse of madness Let’s be real: software in 2025 feels like it’s stuck in a boss fight it can’t win. Every time you open your favorite app, something’s changed and not always for the better. Your battery drains faster, the “new improved” UI hides buttons you used daily, and the performance? Feels like it’s running on a toaster powered by anxiety. You’re not alone. Developers are tired. Users are mad. Product managers are aggressively optimistic. And somewhere in the middle of this chaos, software ships whether it’s ready or not. So the question lingers: Is software actually getting worse… or are we just becoming more aware of its flaws?

“Same title. Same job. Very different outcomes.” If you've ever worked on a dev team, you’ve probably noticed it: not all developers with the same title operate at the same level. Some juniors write better code than mids. Some seniors… well, are just loud middles. So what actually separates a junior developer from a mid-level or senior engineer? Is it years of experience? Code quality? Confidence in meetings? Let’s break it down — responsibilities, problem-solving, communication, mentorship, and growth — with real-life examples and actionable takeaways you can use to level up. Focuses on executing clearly defined tasks. Needs help understanding project context. Often asks, “What should I do next?” 🧠 Scenario: Sarah, a junior dev, gets a ticket: "Add a 'Forgot Password' button." Sh…  ( 5 min )

Let’s talk about something that often gets overlooked in the hustle of automation, syncing your automated test scripts with your test management system! You might think, “Eh, my tests run fine. I’ve got my green ticks on the pipeline. Why bother?” Well, hold onto that thought, because today I’m going to show you why this link is not just a nice-to-have but a superpower for your test automation efforts! What do I mean by Linking? At its core, linking means there’s a direct connection between the test cases you’ve written in your test management tool (like TestRail, Azure Test Plans, XRay, etc.) and the actual automation scripts you’ve coded up in your framework (Cypress, Playwright, Selenium — you name it). This sync can be manual (you link test IDs in your scripts) or fully automated. Wh…  ( 6 min )

As engineers, we use transactions all the time — BEGIN, COMMIT, and maybe a rollback if things go south. But recently, I realized I hadn’t truly internalized what makes those transactions reliable. That curiosity led me to revisit the ACID properties — a foundational concept we all learn early on but rarely pause to deeply understand. What started as a quick refresher turned into a deep dive into atomicity, consistency, isolation, and durability, and how real databases like PostgreSQL and MySQL implement them. Along the way, I discovered that one core mechanism — the Write-Ahead Log (WAL) — is key to both Atomicity and Durability, playing a foundational role in keeping transactions safe and recoverable. In this first part of a multi-part series, I’ll walk through what each property means, …  ( 5 min )

When working with Angular and RxJS, takeUntil is a common operator for unsubscribing from observables, especially in component lifecycle management. However, if you're using takeUntil incorrectly with higher-order mapping operators like mergeMap, switchMap, concatMap, exhaustMap, you may still end up with memory leaks. A common mistake is placing takeUntil before a higher-order operator in your observable pipeline. This seems logical, but it doesn't always behave as expected. When takeUntil is upstream of a higher-order operator, it won't effectively unsubscribe the inner subscription created by that operator. this.counterB$.pipe( takeUntil(this.destroySubject), mergeMap((value) => this.counterA$) ).subscribe(...); In the example above, the outer observable (counterB$) is unsubscribed…  ( 4 min )

GO or GOlang Introduction Go(or GoLang) is a popular low-level programming language developed by Google in 2007. And that's what we are going to cover in this blog. What is GO? How was it developed? Why should you consider learning GO? So let's not waste our time and jump in. GO is a general-purpose programming language. It is statically typed and compiled. It is known for its simplicity of syntax and a better developer experience than other programming languages in the same niche, like: C C++ Rust A statically typed language is one where the type checking is completed at compile time, meaning the data type of each variable (string, integer, etc.) is known before the program runs and cannot be changed afterwards. Many people get confused and think that GO is both statically and dynamically typed because: x := 2 //Dynamically declared (GO's Type interface decides the type). var y int = 4 //Statically declared. Both ways can be used to declare variables in GO. But then why do we say it's statically typed? Because in a statically typed language like GO, you cannot do: x := 2 and then x = "two". Doing this will cause a compilation error. But in dynamically typed languages like JavaScript, you can do the same thing as x = 2 x = 'two' console.log(x) And it will work fine. GO was developed by Google in 2007. The designers wanted to address the issues they felt with the language they used at that time, but keep their useful characteristics. Go was publicly announced in November 2009, and the first version was released in 2012. Now, this language is actively used in the world. It’s Simple and easy, unlike Rust, C++, and C. First Class Concurrency Performance Proven Track Record + Job Demand And that's why you should prefer learning GO.

The other night, I was talking about meta programming to other developers, and at one point someone asked how macros could be used to do meta programming. They were probably thinking about C type of macros, which are powerful but are just text processor tools. Using macros you could have the following code: double Compute() { // doing something return result; } and transform it into: double Compute() { if (_cache.GetValue(out var result) return result; // doing something _cache.SetValue(result); return result; } They are a tool to manipulate code, with code. It allows one to write generic code and have the compiler do the heavy lifting and monomorphize your code. What's meta programming?

In early 2025, I realized something uncomfortable: I was spending hours every day switching between tabs, endlessly scrolling, and jumping between distractions — and I didn’t even realize how often it was happening. Like many developers and students, I use a computer all day. But I noticed a pattern of compulsive behavior that wasn’t productive. I wasn’t just “working online.” I was switching contexts 50+ times an hour — email, YouTube, Reddit, docs, social media, GitHub… repeat. I wanted to understand my dopamine loops — those invisible triggers and habits that push me to seek micro-hits of pleasure instead of focusing on deep work. That’s why I started building Dopamine Tracker — a minimal, privacy-focused tool that: tracks online behavior via a browser extension, stores it in a Supabase backend, and visualizes patterns through a React dashboard. It’s not about guilt or blocking websites — it’s about insight and agency. Right now, the extension logs: Active tab time App switches and focus changes Time-of-day usage Top “dopamine drivers” (based on frequency + context) Everything is stored locally in local storage as for the alpha stage. I’m sharing this journey to: document the technical process (React, Supabase, browser APIs), reflect on design choices and architecture, connect with others working on similar problems. If you’ve ever found yourself working but not really working — this project might speak to you. In the coming weeks, I’ll share devlogs on: implementing dopamine tracking and scoring algorithms designing the extension UI, building the analytics dashboard, Thanks for following along. Let’s see where this goes. Stay mindful, stay focused. — Pietrell  ( 3 min )

Understanding Object References in JavaScript Have you ever changed something you thought was a separate copy, only to find you messed up the original data too? Yeah, that happens a lot if you don't get how JavaScript handles different kinds of copying; deep copy vs shallow copy. JavaScript has these two main ways it thinks about data: by value and by reference. Simple stuff like numbers, strings, booleans, null, and undefined are value types. When you copy them, JavaScript just makes a whole new one. A separate thing entirely. Changing the new one never affects the old one. let a = 10; let b = a; // b gets a copy of the value 10 b = 20; console.log(a); // Output: 10 (a is unchanged) However, objects, arrays, and functions are reference types. When you assign one variable to another, yo…  ( 10 min )

This is a basic Go lang project that shows your age if you know your birth year. In this, you have to input your birth year, and it will take the current year automatically. By using the formula Current Year - Birth Year, it shows your current age. This project is mainly intended to learn how to containerize an application. It is not a Go-focused project but mainly Docker-focused instead. A Dockerfile will be created to build a Docker image and run it inside a container. Once containerized, the application can be run easily using Docker commands on any system that supports Docker, regardless of the host environment. This helps demonstrate the power of containerization and the portability it brings to software development. The project will also serve as a base to practice Docker fundamentals like: -> Writing a Dockerfile -> Building a lightweight image for a Go application -> Running the image as a container -> Understanding how to manage input/output inside the container Overall, this project provides a practical, beginner-friendly example of containerizing a simple application — making it a great starting point for learning Docker and DevOps workflows.

Your phone was running Linux, but you couldn’t just open a terminal and start hacking away like you can on your favourite desktop distro. Android was Linux, but not “Linux Linux.” Fast-forward to 2025, and things are changing-fast. Google is now rolling out native Linux t…  ( 4 min )

In the world of .NET development, understanding the differences between IQueryable and IEnumerable is crucial for optimizing application performance and ensuring efficient data querying. In this article, we will explore the fundamental differences, their use cases, and best practices for leveraging each interface effectively. 🔍 What is IEnumerable? IEnumerable is an interface that allows you to iterate over a collection of objects. It is defined in the System.Collections namespace and works best with in-memory data collections like lists or arrays. Key Characteristics: 1- In-memory Processing: All operations with IEnumerable are performed in memory. 2- Deferred Execution: It supports deferred execution, meaning the query is only executed when you iterate over it (e.g., with foreach). 3-…  ( 4 min )

Common Malware Types Introduction: Malware, short for malicious software, encompasses various programs designed to damage, disrupt, or gain unauthorized access to computer systems. Understanding common malware types is crucial for effective cybersecurity. Prerequisites: A basic understanding of computer operating systems and network protocols is helpful, though not strictly necessary to understand the core functionality of these malware types. Types of Malware: Viruses: These self-replicating programs attach themselves to other files and spread when those files are executed. They can range from relatively harmless annoyances to highly destructive. Example: A virus might add itself to every .doc file on a system. Worms: Unlike viruses, worms can replicate independently and spread acr…  ( 4 min )

Everyone tells you how to write perfect code. But no one tells you how easy it is to mess things up, especially when you're just starting out. 1. Writing Code Without Planning Anything: I jumped straight into coding because I was too excited. The Result: Now, I sketch out a quick plan, even 10 minutes of thinking saves hours of debugging. 2. Copy-Pasting Stack Overflow Without Understanding: I copied a solution that worked—until it didn’t. The Result: I still use Stack Overflow, but I make sure I understand every line I paste. 3. Ignoring Git Until the Last Minute: I lost an entire day’s work because I forgot to commit. The Result: I commit after every major change and push regularly. Git is now my safety net. 4. Not Reading the Documentation: I wasted hours searching for answers that were literally in the first paragraph of the docs. The Result: First I read the docs, then surf the internet for information. Even the order of this matters. 5. Overengineering Everything: I tried to build “the perfect solution” with 10 extra features I didn’t need. The Result: Build version 1 very simple. Improve later. Launch ugly, improve fast. 6. Not Asking for Help: I stayed stuck on a bug for 3 days because I didn’t want to “look dumb” by asking help. It was a terrible mistake. The Result: I now ask questions early—online, Discord, dev forums. No shame in learning. 7. Testing Code in Production: I pushed code live without testing. The Result: I test locally, then deploy to staging, then go live. Never gonna skip testing again. Final Thoughts: Which one hit you the hardest? Drop it in the comments.  ( 4 min )

What are Push Notifications ? Push notifications are messages sent from an app or website to a user's device, even when the app or site isn’t actively open. They appear as pop-up alerts, banners, or notification icons on devices like smartphones, tablets, and computers. The mechanism with which these "Push Notifications" work is usually the use of some sort of background processes, these processes maintain a persistent connection with the designated "Push Server" depending on their device (in the case of Native Push) or their navigator (in the case of Web Push). There's two types of Push Notifications: Native Push: This one usually is linked directly to the Operating System of the Device where Push notifications were activated, for example, Windows, MacOS, Android or IOS.

Hello! 👋 I’m working on a solo project to build a no-code quantitative trading backtesting platform — a tool that enables users to visually create trading strategies, backtest them on historical market data, and analyse their performance. I know nothing about Quantitative trading but I would like to learn about it just for fun. My own personal goal for this project is ultimately to learn more about quant and to try building a full project by myself. The reasoning behind making a visualiser in particular is because I find that visualisers are really helpful for understanding new concepts, the issue with quantitative trading however, is that there's a big learning curve and the majority of resources are hidden behind a paywall, making just learning the basics quite difficult without diving …  ( 4 min )

I used to work at a small startup in the midwest. Like real small. We had maybe 12 people total and I was doing backend stuff basically by myself. We built software for manufacturing companies and it was alright but kind of boring and nobody outside our town ever heard of us. I was there for a little over a year and felt like I was just stuck. I started thinking maybe I could get into a bigger company but I didn’t really know how to even start. I had a LinkedIn and a GitHub and I sent out resumes but I either got ghosted or got interviews I bombed. I could code fine but I would totally freeze on system design and I’d second guess myself a lot in interviews. Honestly I think I just lacked confidence and didn’t know how to play the game.

In software design, a God Object (or God Class) is a class that knows too much or does too much. It's a common code smell that tends to emerge as a system evolves without proper boundaries. A God Object violates the Single Responsibility Principle by taking on multiple responsibilities. It typically centralizes control and knowledge of many parts of a system—handling tasks that should be delegated to other specialized components. Even experienced developers can fall into this trap, usually due to: Moving fast: Prioritizing speed over modularity in early stages. Avoiding perceived complexity: Putting logic in one place “for convenience.” Fear of breaking things: As the class grows, refactoring becomes scarier. Lack of clear ownership boundaries: Developers aren't sure where logic belongs. L…  ( 4 min )

I've created a "tune API" for the next version of VarMQ. Essentially, "Tune" allows you to increase or decrease the size of the worker/thread pool at runtime. For example, when the load on your server is high, you'll need to process more concurrent jobs. Conversely, when the load is low, you don't need as many workers, because workers consume resources. Therefore, based on your custom logic, you can dynamically change the worker pool size using this tune API. In this video, I've enqueued 1000 jobs into VarMQ, and I've set the initial worker pool size to 10 (the concurrency value). Every second, using the tune API, I'm increasing the worker pool size by 10 until it reaches 100. Once it reaches a size of 100, then I start removing 10 workers at a time from the pool. This way, I'm decreasing and then increasing the worker pool size. Cool, right? VarMQ primarily uses an Event-Loop internally to handle this concurrency. This event loop checks if there are any pending jobs in the queue and if any workers are available in the worker pool. If there are, it distributes jobs to all available workers and then goes back into sleep mode. When a worker becomes free, it then tells the event loop, "Hey, I'm free now; if you have any jobs, you can give them to me." The event loop then checks again if there are any pending jobs in the queue. If there are, it continues to distribute them to the workers. This is VarMQ's concurrency model.  ( 3 min )

In modern React development, user interactivity is everything. Mouse events form the core of how users engage with your components—from clicking a button, dragging a file, to hovering over content for context. In this article, we’ll deep dive into the wide array of mouse and drag-related event handlers available in React + TypeScript. We'll explore their purpose, use cases, and demonstrate best practices through an interactive math-based UI. Whether it's clicking a calculator button or dragging a number into a math equation, mouse events allow users to manipulate the UI directly. Mastering these events allows you to build: Custom context menus Drag-and-drop editors Interactive games Advanced canvas-based charts React uses a synthetic event system—a cross-browser wrapper around the browser’…  ( 4 min )

When people hear "software engineer," the first image that pops into their mind is someone furiously typing code, probably in a dark room with six monitors and a cup of cold coffee. But is that all there is to it? Not even close. In this post, let’s explore what it really means to be a software engineer — beyond the code. Being a great software engineer isn’t just about knowing 12 different JavaScript frameworks. It's about understanding problems and communicating solutions. Can you explain a complex bug to your product manager in simple terms? Can you write clear, helpful documentation? Can you give constructive feedback in code reviews? 💡 If you're not improving your communication skills, you're limiting your growth. You’ll often face challenges that have nothing to do with code: Ambiguous requirements Legacy systems with no documentation Interpersonal team conflicts Sometimes, you spend more time on Slack than in VS Code. And that’s okay. That’s part of the job. You don't just learn programming languages — you learn people, processes, and priorities. The most successful engineers I've met are not the ones who knew everything — but the ones who kept learning every day. Burnout is real. Sleep deprivation doesn’t make you a hero. Take breaks. Set boundaries. Eat lunch away from your screen. Because your brain is your best asset — and it needs rest to work its magic. Software engineering is a journey — and the code is just one part of it. The next time someone asks you what you do, don’t just say "I write code." Because that’s what you really do. 💬 What’s something you've learned outside of code that made you a better developer? Drop your thoughts below — let's talk!  ( 4 min )

Understanding DNS: How Domain Names Become IP Addresses In our previous blog post, we covered domains and their various aspects. Now, let's dive deeper into DNS (Domain Name System) - the backbone of internet navigation. DNS, or Domain Name System, is essentially a translator for the internet. Its primary function is simple yet crucial: it converts human-friendly domain names (like example.com) into machine-readable IP addresses that computers use to identify each other. Without DNS, you'd need to memorize numeric IP addresses instead of easy-to-remember domain names. Before we explore how DNS works, let's clarify two important roles that make the domain system possible: A registry is an organization that manages a specific top-level domain (TLD) For example, Verisign manages the .com an…  ( 8 min )

Key points: Bitcoin’s rally to $105,980 has traders predicting new all-time highs this week. Traders lift their end-of-year Bitcoin price targets to $200,000 based on technical factors and institutional investor adoption.  Bitcoin (BTC) has been stuck in a narrow range for the past few days, but the rally above $105,500 on May 18 increases the possibility of an upside breakout. Popular trader Alan said in a post on X that Bitcoin could soar to $116,000 early next week. Another bullish voice was that of Bitwise chief investment officer Matt Hougan. While speaking to Cointelegraph, Hougan said that a supply shock due to increased institutional demand could propel Bitcoin to $200,000 by the end of 2025. He expects seller exhaustion to occur at the $100,000 level. Crypto market data daily …

Attorneys for Tornado Cash developer Roman Storm filed a motion asking the court to reconsider the motion to dismiss the case due to the prosecution withholding exculpatory evidence in the form of communications with the Financial Crimes Enforcement Network (FinCEN) dating back to 2023.

Opinion by: Igor Mandrigin, co-founder and CTPO of Gateway.fm Every couple of weeks, it seems another layer 2 rolls out, much to the chagrin of some Web3 industry commentators who are concerned about fragmentation. A recent Gemini Institutional Insights report actually noted how a new Ethereum L2 solution is launched approximately every 19 days. In response to the seemingly endless conveyor belt of new zkEVMs and optimistic rollups coming to market, the chorus of criticism continues to grow louder: “This is definitely the saturation point, no more chains are needed.” Some of the most outspoken critics of L2s argue that L2s are redundant, but this is narrow thinking. In many ways, the idea that creating new L2s should be slowed down is like arguing that there were too many websites in 1998.…

Hong Kong police arrested 12 people involved in a cross-border money laundering scheme that relied on crypto and over 500 stooge bank accounts to launder HK$118 million ($15 million), local news outlets reported. The syndicate was dismantled on May 15, resulting in the arrest of nine men and three women in mainland China and Hong Kong. The suspects allegedly recruited others to open bank accounts to receive proceeds from fraud cases, which were then converted into crypto at crypto exchange shops to launder the illicit funds, Hong Kong Commercial Daily reported on May 17. The criminal organization rented a residential unit in the Hong Kong neighborhood of Mong Kok to plan and carry out its money laundering activities. Of the $15 million laundered, more than $1.2 million was linked to 58 re…

Buy Me a Coffee☕ *Memos: My post explains variable assignment. My post explains iterable unpacking in variable assignment. My post explains parameters and arguments. My post explains positional-only parameters in function. My post explains keyword-only parameters in function. My post explains positional-only parameters and keyword-only parameters together in function. Lambda: is the function which can be stored in a variable and parameter. is an expression. cannot be used with pass. is almost same as a normal function except these above. You can see Lambda Expressions You can use Lambda as shown below: # Equivalent v1 = lambda: 2 # def func(): return 2 v1 = lambda x: x # def func(x): return x v1 = lambda x, y: x+y # def func(x, y): return x+y v1 = lambda x, y=3: x+y # def func(x, y=3): return x+y v1 = lambda x=2, y=3: x+y # def func(x=2, y=3): return x+y v1 = lambda x=2, /, y=3, *, z=4: x+y+z # def func(x=2, /, y=3, *, z=4): # No error # return x+y+z v1 = v2 = lambda: 2 v1, v2 = [lambda: 2, lambda: 3] # No error v1 = lambda: pass v1 = def func() return 2 v1 = func() return 2 # SyntaxError: invalid syntax v1 = lambda: 2 print(v1()) # 2 v1 = lambda x: x print(v1(2)) # 2 print(v1(x=2)) # 2 v1 = lambda x, y: x+y print(v1(2, 3)) # 5 print(v1(2, y=3)) # 5 print(v1(x=2, y=3)) # 5 print(v1(y=3, x=2)) # 5 v1 = lambda x=2, y=3: x+y print(v1(6)) # 9 print(v1(x=6)) # 9 print(v1(y=5)) # 7 print(v1(6, 5)) # 11 print(v1(6, y=5)) # 11 print(v1(x=6, y=5)) # 11 print(v1(y=5, x=6)) # 11 v1 = lambda x=2, /, y=3, *, z=4: x+y+z print(v1(6, 5, z=4)) # 15 print(v1(6, y=5, z=4)) # 15 print(v1(6, z=4, y=5)) # 15 v1 = v2 = lambda: 2 print(v1(), v2()) # 2 2 v1, v2 = [lambda: 2, lambda: 3] print(v1(), v2()) # 2 3 def func(x=lambda: 2): print(x()) func() # 2 func(lambda: 4) # 4 func(x=lambda: 4) # 4  ( 4 min )

A Tabela Verdade é uma ferramenta da lógica que mostra todas as possibilidades de verdade ou falsidade de uma proposição ou conjunto de proposições. Ela é usada para analisar frases com conectivos lógicos, como "e", "ou", "se... então" e "se e somente se", e entender quando uma frase é verdadeira ou falsa com base nas partes que a compõem.

Domains are to the internet what names are to humans, making identification simple and intuitive for everyone. Just as we give people names instead of describing their physical characteristics each time we refer to them, domains give websites and online resources readable names instead of complex numerical addresses. When you type 'google.com' instead of having to remember a string of numbers like '172.217.168.238', you're benefiting from the domain name system that makes the internet accessible to everyone. One key difference from human names is that while many people can share the same name in the real world, a single domain can only point to one destination at a time on the internet. However, you can have multiple domains all pointing to the same resource, similar to having several nick…  ( 9 min )

Chapter 1: The Birth of a Visionary (Pre-1994) The early 1990s were a time of tectonic shifts in both politics and technology. The Cold War had just ended, giving way to a wave of globalization. Meanwhile, the internet, once a military and academic curiosity, was on the verge of becoming commercially viable. In 1990, Tim Berners-Lee introduced the World Wide Web, and by 1993, web browsers like Mosaic were making the internet accessible to the average user. Amid this digital dawn, a Wall Street executive named Jeff Bezos was working at D.E. Shaw, a prestigious hedge fund. Bezos, a Princeton graduate with a background in computer science and electrical engineering, came across a stat that changed everything: internet usage was growing at 2,300% per year. Bezos immediately recognized the co…  ( 6 min )

Hello Dev.to community! 👋 I’m excited to share my journey as a developer and how I managed to improve my coding skills significantly by focusing on building small practical projects. Here are some tips that worked for me: Start small: Don’t try to build complex apps from day one. Begin with simple projects like a to-do list or a calculator. Practice regularly: Dedicate at least 30 minutes every day to coding. Learn from mistakes: Don’t be afraid to break your code. Debugging is a great way to learn. Use online resources: Platforms like freeCodeCamp, MDN, and Stack Overflow are fantastic. Share your code: Use GitHub or Dev.to to share your projects. Getting feedback helps you improve. If you’re starting your coding journey or looking for motivation, keep pushing forward — consistency is key! Feel free to follow me for more coding tips and project ideas.

In Go, the Option pattern (also known as the configuration pattern or constructor pattern) is a commonly used design pattern, primarily for handling function parameters, especially when a function has many optional parameters. By using the Option pattern, we can pass and configure function parameters in a flexible and extensible way, avoiding the maintenance challenges and complexity of traditional methods with too many parameters. Let’s take a look at how the Option pattern is used in Go, analyze its implementation principles, and help you better understand how to apply this pattern in real-world projects. When constructing complex objects in Go, we often encounter the following pain points: // Example problem: Parameter explosion and difficult maintenance func NewServer(addr string, port…  ( 6 min )

Predictability, Pre-Recorded Reality, and AI Evolution: From Dilbert to LivinGrimoire Are We Just Predictable Scripts? The Dilbert Dilemma In an episode of Dilbert, the protagonist unwittingly has a conversation—not with his mother, but with a recording of her usual responses. She had pre-recorded their exchanges because Dilbert was so predictable, his side of the conversation could be anticipated without her present. Even when Dilbert realized he was talking to a recording, it kept responding accurately to him, as though their conversation were still fluid and natural. This presents a stunning thought experiment: how could Dilbert prove he was talking to a recording? What test could he run to confirm whether the responses were truly dynamic or just well-constructed predictions? …  ( 5 min )

🌍 A Bit of History — Where HTTP Came From Back in 1989, Tim Berners-Lee invented the World Wide Web (WWW). But it wasn’t just websites — it was a system of protocols, and one of them was HTTP: the HyperText Transfer Protocol. HTTP was designed as a simple way to send hypertext (HTML) documents between computers. This allowed the user to experience a more dynamic and interactive way to access information. Since then, HTTP has evolved (currently at HTTP/3), but its core idea hasn’t changed: "Let the client ask, and let the server answer." That basic principle powers nearly every web app today. Without HTTP, the internet would not look, feel, or behave as it does. 📸 Request vs response: When your browser opens a website, it sends an HTTP request. The server replies with an HTTP respo…  ( 4 min )

A Quick Guide to Getting LinkedIn OAuth Working Correctly LinkedIn authentication is a powerful feature to add to your Next.js application using NextAuth.js, but the default configuration can often lead to issues — especially when trying to fetch user details like email, name, and profile picture. In this article, I’ll walk you through how I solved this issue by customizing the LinkedIn provider configuration in NextAuth.js. Using the default LinkedInProvider setup from next-auth/providers/linkedin may not always return complete user information such as email or profile picture. import LinkedInProvider from "next-auth/providers/linkedin"; providers: [ LinkedInProvider({ clientId: process.env.LINKEDIN_CLIENT_ID, clientSecret: process.env.LINKEDIN_CLIENT_SECRET, }) ] This …  ( 4 min )

Supabase Auth already has an Auth Users table. The image might be blurry. If you visit the project in your Supabase Account, you can check your Auth table of the project. If you wanted to add additional data to your a User table, it's likely you've wondered 🤔 Should you create your own, separate profiles (or users) table in Supabase and link it with the Supabase Auth Users table? OR Should you extend the existing Supabase Auth Users table? Supabase’s recommended pattern is to create a separate profiles (or users) table in the public schema rather than altering the built-in auth.users table. The auth.users table (in the auth schema) is managed internally and isn’t exposed via the auto-generated API. Supabase maintainers explicitly advise “It is not recommended to modify the schema…  ( 4 min )

If you're using Rancher Desktop and ran into this error when running supabase start: supabase_vector_project container is not ready: unhealthy You're not alone — and here's what likely caused it (and how to fix it): Supabase CLI uses Docker under the hood, and it expects to communicate with the Docker Engine via a well-behaved socket or TCP endpoint. Rancher Desktop (especially with containerd or non-default networking setups) can cause issues with: Port forwarding DNS resolution Health checks (like with the vector container) This often results in the vector container going into an unhealthy state, crashing the entire setup. I recommend switching to Docker Desktop if you're planning to use Supabase CLI locally. On Docker Desktop: Supabase CLI is better supported and more stable If needed, enable: "Expose daemon on tcp://localhost:2375 without TLS" (from Docker Desktop settings → General) This change instantly fixed the issue for me. Hope this saves someone hours of debugging. Feel free to comment if you've found a better way!  ( 3 min )

Just because AI tokens are cheap today doesn’t mean they’ll stay that way. When cloud adoption peaked around 2015, everyone migrated to “save money.” But many teams didn’t fully understand their on-prem costs, nor did they have a realistic plan for managing spend once they migrated. It’s as though we forgot about all our best practices. In 2015, cloud spend was projected to grow from $49B to $67B by 2018. In 2023? It hit $563.6 billion, with $678.8 billion forecasted for 2024 Alongside that growth came tool sprawl, security risk, and unexpected costs. Sound familiar? AI token usage is on a similar path only this time, the underlying mechanics are even more opaque. Let’s demystify it. A “token” is just a chunk of text (words, punctuation, etc.) that an AI model processes. But the cost and i…  ( 5 min )

The first time I encountered state management in Vue, I was overwhelmed. I was building a simple dashboard application that had grown from a weekend project into something much more complex. Components were passing props six levels deep, and emitting events that would get lost in the hierarchy. I remember thinking, "There has to be a better way." That's when I discovered Vuex. It felt like finding an oasis in the desert. But as time passed and my projects grew more complex, I started to feel the pain points. The boilerplate code, the mutations that seemed redundant, the TypeScript support that always felt a bit bolted on rather than built-in. Then came Pinia, and it was like a breath of fresh air. In this article, I want to share my journey with Pinia, how it transformed my approach to sta…  ( 15 min )

First let me say that the reason I’m writing this is because I’ve read many posts of people struggling with the current job market, and I feel you. I just went through what you’re going through and I want to help you. I’m not preaching from an ivory tower and I’m not a guru selling you a service. I applied for 500+ on LinkedIn and some other boards only to get the same automated rejection message over and over again. Step 1 — Leave your ego behind, understand these were not actual people that misjudged you, and that it’s not a measure of your worth. If you know you’re good, you can’t let some bot email bring you down in any way.

Will Ai replace programmers" by AI The idea that "AI will replace programmers" is a hot (and often exaggerated) debate. Here’s my take: AI Won’t Replace Programmers—But It Will Change the Job. -AI is a tool, not a replacement. Just like calculators didn’t replace mathematicians, AI (like GitHub Copilot, ChatGPT, or Devin) will automate parts of coding (boilerplate, debugging, docs) but can’t: 1 Understand complex business needs or ambiguous human requirements. 2 Design creative architectures or novel solutions. 3 Make ethical/critical decisions (e.g., privacy, security, trade-offs). Programming is more than writing code. It’s problem-solving, collaboration, and adapting to chaos—things AI struggles with. The “Junior Dev” Role Might Shrink AI can already: Generate simple code snippets. Fix common bugs. Answer Stack Overflow-style questions. Entry-level tasks may get automated, forcing new programmers to upskill faster (e.g., focus on system design, domain expertise). Future Programmers Will Look Different Shift from “writing code” to “orchestrating AI.” Example prompts: “Design a scalable API for X, optimize for cost, and explain trade-offs.” More emphasis on: Soft skills (stakeholder communication, UX empathy). Domain knowledge (healthcare, finance, etc.). AI-augmented workflows (prompt engineering, validation). Historical Parallels Fear: “High-level languages will kill coding!” → Instead, demand exploded. Fear: “No-code tools will replace devs!” → They just enabled non-devs. AI will likely create new roles we can’t yet imagine. Bottom Line Worst-case: Low-end coding jobs decline; programmers need to adapt. Best-case: AI removes grunt work, letting devs focus on harder, more meaningful problems. My advice: Learn to leverage AI, but double down on uniquely human skills (creativity, critical thinking, leadership). What’s your take? Excited or  ( 3 min )

Enable or Disable console.log Globally in JavaScript Sometimes, during development or debugging, you need to quickly enable or disable logging globally across your entire JavaScript application. Here's a straightforward approach to achieve this. console.log Before we override the console.log function, it's crucial to keep a reference to the original function. let original_console_log = console.log; This ensures you can restore the original functionality anytime you want. Next, create a function that can toggle logging on and off by replacing console.log. let logging_enabled = true; function set_logging(enabled) { logging_enabled = enabled; console.log = enabled ? original_console_log : function () {}; } Here's what's happening: When enabled is true, console.log points back t…  ( 4 min )

Advanced Use Cases for Proxy in Data Validation Introduction to Proxy Introduced in ECMAScript 2015 (ES6), the Proxy object allows you to create a wrapper for another object, enabling you to define custom behavior for fundamental operations (like property lookup, assignment, enumeration, function invocation, etc.). This allows for considerable flexibility in handling objects. As applications grow in complexity, the need for robust validation strategies becomes vital—especially when dealing with data from various sources such as APIs, user input, or databases. While Proxy is often showcased with simple examples of intercepting property access, its true potential lies in advanced use cases such as data validation. Prior to Proxy, JavaScript relied on direct methods (such as co…  ( 6 min )

As we navigate through 2025, a significant paradigm shift is occurring in the AI landscape. While much attention has been focused on increasingly massive language models with hundreds of billions of parameters, a countercurrent has emerged: Small Language Models (SLMs). These lightweight yet powerful models are gaining tremendous traction among developers, enterprises, and researchers for their efficiency, practicality, and accessibility. SLMs, typically defined as models with fewer than 10 billion parameters (and often less than 1 billion), are proving that bigger isn't always better when it comes to solving real-world problems. Their rise represents a maturing of the AI field, moving from raw capability demonstrations toward optimized, targeted solutions. Small Language Models offer comp…  ( 7 min )

Em um cenário onde a agilidade deixou de ser diferencial para se tornar pré-requisito, ainda existem empresas que tratam infraestrutura como um custo fixo, estático, centralizado — e, muitas vezes, emocionalmente preso à stack de um único fornecedor. Essa escolha, além de técnica, é cultural. E, quase sempre, onerosa. Infrastructure as Code (IaC) não é sobre versionar configurações. A pergunta não é mais “por que usar IaC?” Quantas decisões financeiras, técnicas e operacionais sua empresa está deixando de tomar por não conseguir abstrair a própria infraestrutura? Porque enquanto sua equipe debate qual cloud é "melhor", a concorrência já está rodando workloads em múltiplos provedores, otimizando custo e latência em tempo real. Uma infraestrutura agnóstica não é luxo. É alavanca. Funções específicas com melhor suporte em outro ambiente? Roda lá. Região mais próxima do usuário? Você escolhe. Não é a cloud que decide. Quem domina a infraestrutura como código, domina o custo, o risco e a mudança. O problema não é a nuvem. Sem IaC, sua empresa não tem flexibilidade. Otimização não é uma planilha. É arquitetura. IaC não é sobre “como rodar melhor”. A infraestrutura deixou de ser suporte. E quem ainda não entendeu isso, vai continuar pagando caro por aquilo que deveria estar controlando.  ( 4 min )

There are a lot of design patterns, techniques, and ideas around us—both online and offline. An architect can always look towards them for inspiration. But it is very important to ignore the noise. In this series of articles, we will follow the book Righting Software by Juval Löwy, which refers to the entire concept of project and system design as "The Method". We will also refer to this idea as The Method throughout the series. By system design, we mean the design of the architecture, not the detailed design—which deals with how classes, interfaces, and contracts should be built within a component. Detailed design can be discussed in another series. There is a common misconception that a good architect needs decades of experience building systems to know what the right design decisions ar…  ( 5 min )

Over my 15+ years in web development, I've witnessed frameworks rise and fall, from jQuery to Angular, from Redux to React Query, and now to Remix.js. As we approach mid-2025, Remix.js has evolved into a powerful framework for creating fast, scalable, and SEO-friendly blogs.

When you’re building an app in ASP.NET Core, it’s easy to fall into the trap of just writing code that “works.” Especially when deadlines are tight. But if you’ve ever looked back at your project and thought, “Ugh, this is a mess,” then you know why architecture matters. Think of software architecture like the blueprint for a house. You wouldn’t build a house without planning where the walls, plumbing, and electrical systems go — same goes for your code. Here’s a common scenario I see all the time: Code Rot — where the codebase gets harder and harder to work with over time. The God Controller [HttpPost] public async Task Create([FromBody] OrderDto dto) { var order = new Order { CustomerId = dto.CustomerId, Total = dto.Total, CreatedAt = DateTime.UtcNow }; _context.Orders.Add(order); await _context.SaveChangesAsync(); return Ok(order.Id); } Looks simple enough, right? But think about what happens when you need: Good architecture gives you practical benefits: Yes, .NET is powerful. Yes, EF Core makes it easy to get started quickly. But most tutorials and templates push you toward patterns like: In this series, we’ll walk through real architectural patterns used in modern .NET applications — not just theory, but examples you can actually use in your next project. • Part 2: Layered Architecture – Classic, simple, and still useful. You don’t have to be at a huge company or working on a massive enterprise system to care about architecture. Even a small app can benefit from a bit of structure. If you're tired of messy codebases, hard-to-test logic, or struggling to add features without breaking things, this series is for you. Stick around — we'll turn those spaghetti controllers and thin services into something maintainable, scalable, and enjoyable to work with.  ( 5 min )

Originally published on Medium. Sharing what actually works (and what doesn’t) when using ChatGPT to plan real-world frontend features. When I start building a new feature, my biggest challenge isn’t the code — it’s deciding where to start. I used to open my editor with a vague idea like: “Build login page.” Ten minutes later, I’d have five tabs open, three half-written files, and no direction. Then I started using ChatGPT — not as a boss, but as a planning partner. Here’s how I use it to move faster without getting lost, and also where it sometimes fails. Instead of: “Build dashboard,” I ask: “Break down steps to build a responsive dashboard in Next.js.” It usually gives me: Set up layout Add sidebar, header Fetch data from backend Render UI components Handle empty/loading/error…  ( 4 min )

The role of Middleware in distributed systems Architectural Styles and Middleware (Middleware) Chapter 2.3 "Architectures vs Middleware" The Middleware Role Middleware is an intermediate layer between applications and distributed platforms. Its key task is to ensure transparency of distribution, hiding from applications the complexities associated with data distribution, processing and management. The connection of Middleware with architectural styles In practice, middleware often implements a specific architectural style: Object-oriented style: for example, CORBA (Common Object Request Broker Architecture), where interaction is built through remote objects.

If you’ve been exploring AI or machine learning lately, you might have come across the terms embeddings and vector search. At first, they sound a bit technical, but they’re actually super cool and powerful ideas that help machines understand meaning — not just keywords. Imagine you want a computer to understand words, images, or even sounds. But computers don’t really get language the way we do. So what do we do? We turn these things into numbers. More specifically, embeddings convert data — like a word or a picture — into a list of numbers called a vector. These vectors live in a kind of “number space,” where the position of each vector captures the meaning of the original thing. Because items with similar meaning end up as vectors close to each other in this space. For example, the words…  ( 4 min )

Introduction The combination of React's component architecture with Tailwind CSS's utility-first approach has emerged as a compelling solution for modern web development. This integration addresses several pain points in traditional CSS methodologies while maintaining the flexibility needed for complex applications. Tailwind's utility classes work harmoniously with React's component model by keeping styles tightly coupled with their corresponding components. This eliminates the cognitive overhead of maintaining separate stylesheets and reduces the likelihood of styling conflicts in large applications. Tailwind's predefined design tokens (spacing scales, color palettes, typography settings) create consistency across React components without the need for custom CSS variables or style d…  ( 5 min )

go_router is one of the most popular package for managing navigation in a Flutter application, and since it became part of the Flutter team, it has become the main recommended solution. It's very easy to use, yet feature-rich. However, with the introduction of ShellRoute, observing the navigation flow in your app and having routes that are "aware" of navigation changes has become more difficult. As highlighted in this issue, when you add a ShellRoute, the app loses reactivity to route changes: the NavigationObserver is no longer triggered. While waiting for an official fix or built-in solution from the Flutter team, we can still implement route-aware behavior by listening to the GoRouterDelegate. The following code listens to the GoRouterDelegate throughout the widget's lifecycle and uses …  ( 4 min )

A few months ago, my manager assigned me to a project that required improving its search functionality. The team initially considered Elasticsearch as the primary solution, though they were open to exploring alternatives. I researched the topic and discovered PostgreSQL's full-text search. Since our data was already stored in PostgreSQL, I compared the two tools. The application I worked on served private users and had strict privacy regulations, with complex conditions determining who could view or edit specific data within the company. These intricate queries proved challenging for Elasticsearch to handle effectively, while PostgreSQL's full-text search, being built on top of SQL syntax, required no extra work to handle this. It also integrates seamlessly with our existing database, req…  ( 8 min )

Whether you’re debugging a stubborn production issue or architecting a scalable system, the nature of software development is deeply problem-solving at its core. Yet we rarely take a step back and ask: Are we solving problems effectively? Turns out, a Hungarian mathematician from the 20th century has some timeless advice for us. This post dives into some gold from George Pólya’s classic book, How to Solve It, and shows how its common-sense techniques originally meant for mathematics,are surprisingly useful for software engineers. Pólya's core idea is that general, common-sense questions help solve all kinds of problems,not just math ones. Consider these: What is the unknown? What are the data? What is the condition? These aren't math questions—they’re universal. They work whether you're …  ( 5 min )

Continuing on the topic of template engines, I would like to share my thoughts on the power of template engines, and how it relates to the power of abstractions in programming. First, let us look at the classification of template engines I have listed in my previous post: Logic-less: The template engine does not allow any logic in the template. All the logic is pre-applied to the variable content, our data, before it even arrives at the template engine. A typical example is Mustache. Logic-capable: The template engine allows you to define some logic in the template, such as not only what, but also when and how to display it. A typical example is Jinja2. Logic-full: Such template engines allow you to define any arbitrary logic in the template, by allowing you to even execute code in the …  ( 7 min )

If you're building an online store and looking for a sleek, modern, and responsive template — Tailstore might be just what you need. Built entirely with Tailwind CSS, this free eCommerce template is perfect for developers, indie makers, or startups who want to move fast without compromising design and usability. As a developer, I often find myself reinventing the wheel — especially when starting new eCommerce projects. Either the templates are bloated, outdated, or locked behind paywalls. So I decided to build Tailstore, a clean and lightweight Tailwind CSS eCommerce template that anyone can use, adapt, and scale. Tailstore is designed with performance and simplicity in mind. No dependencies beyond Tailwind. No overcomplications. Just clean HTML and reusable components — perfect for customization or integration into your favorite stack (Laravel, Next.js, Nuxt, etc.). Here's what Tailstore comes with out of the box: Responsive Hero Slider (Swiper.js) to highlight products or promos Brand Carousel to showcase partnerships Latest / Popular Products Grid Blog Section for content marketing Newsletter Signup Form Product grid with filters (categories, price range) Single product view with: Image gallery Tabs for description / reviews Social sharing buttons Authentication Clean Register / Login pages 404 error page Shopping cart and checkout flow with promo code support Built with Tailwind CSS Uses Tailwind 4 utility classes Fully responsive layout Easily extendable with Tailwind UI or your custom components Mobile-first and minimal Tech Stack No JavaScript frameworks — you choose how to integrate it! 📦 Use Cases Tailstore is great for: MVPs and startup demos Learning Tailwind CSS through real-world layout structure Integrating with headless CMS (like Sanity, Strapi) Customizing for Shopify Hydrogen / Next.js Commerce You can download, clone or fork the project here: website spacemadev/tailstore4 It’s open-source, MIT-licensed, and ready for your next idea.  ( 3 min )

Dica de TI será uma série de posts com conteúdo sobre tecnologia. São posts curtos explicando alguns conceitos. Nos exemplos a linguagem usada será: Java Concatenar significa "colocar junto", “juntar-se”, “ligar-se” Para concatenar duas String, usa-se o método concat. Note que, já que o tamanho de uma String não pode mudar, a concatenação resulta na criação de um novo objeto. Também pode-se usar o operador + para a concatenação. Por exemplo, no trecho de código abaixo, a mesma linha é impressa duas vezes: String s1 = "Olá "; String s2 = "Mundo!"; System.out.println( s1.concat( s2 ) ); System.out.println( s1 + s2 ); As strings no java são imutáveis, ou seja, seu valor não muda A partir do java 15 tem um recurso chamado text blocks onde é possível formatar a string da forma como você quer que apareça, pode colocar parágrafo e espaço.

DevSecOps: The Ultimate VPS Security Guide 1. Introduction to SSH SSH (Secure Shell) is a cryptographic protocol for secure remote server management and file transfers. It’s the modern replacement for insecure protocols like Telnet. Pro Tip💡: Use an SSH config file to manage multiple server connections efficiently. Most OSes (Linux, macOS, Windows) include built-in SSH clients. 2. Connecting to Your VPS Connect to your VPS using the root credentials and IP address provided by your host: Ex: ssh root@194.68.123.45 First Connection: Verify the server’s fingerprint to prevent man-in-the-middle attacks. SSH stores it locally for future validation. 3. Server Hygiene: System Updates Regular updates are your first defense against vulnerabilities.

Written Date: 5/17/2025 For the last 2 years I've been using AI to drive most of my development efforts. It wasn't called "vibe coding" then, but it was just as frowned upon. The phrase "AI slop" was coined and tossed around willy nilly. Under every rock and around every corner you would find an expert ready to jump out and say that AI was overhyped. It was tenuous time to be using AI for helping you code. I will admit that the concerns brought forward were true then and are still mostly true now. However, there were these moments of brilliance that would shine through. These felt like samples of what was to come in the future, something that we would eventually consider to be just plain normal. I've held on to the inspiration and hope that came from those moments of clarity and brilliance…  ( 4 min )

Let's cut to the chase: Congressional Records are gold mines of political data, but they're trapped in PDFs and scattered across congress.gov. Yeah, there's an API, but it just gives you more PDFs or links to HTML pages. Not exactly AI-friendly. I needed plaintext, I needed it in bulk, and I needed it yesterday. So I built a Python tool that: Grabs data through the congress.gov API Ignores those pesky PDFs Extracts clean plaintext from the HTML pages Organizes everything neatly Why plaintext? Because you can actually do something with it! Search it, analyze it, feed it to AI models, cite specific sentences, or just read it without your eyes bleeding from PDF formatting. The tool leverages several key strategies to efficiently download records: The script uses the official congress.gov API,…  ( 6 min )

Alright, let's cut to the chase. You're building a React MVP. You need to be fast, lean, and focused on validating your core idea. So why, oh why, are you already thinking about t('user.welcome.message.short')? Internationalization (i18n) is crucial for global reach, no doubt. But for an MVP, traditional i18n setup is often a premature optimisation, a time sink when you should be shipping and iterating. It means wrestling with JSON files, getting lost with keys everywhere in your app, and losing velocity at a time you shouldn't. i18n-keyless This is where the "keyless" philosophy, then first time embodied by i18n-keyless, becomes your MVP's best friend. The concept is refreshingly simple: Just write your UI text directly in your components, in your main language. That's it. import * as I…  ( 5 min )

If you’re a web developer like me, you’ve probably styled a form before. And if you’re anything like me, you’ve tried to be helpful — maybe you added some color changes with input:valid or input:invalid, outlined fields, maybe even threw in a little transition effect. But then this came to your mind: Wait, why is this field showing up as valid before the user even typed anything? 🤦 Want smart web dev tips like this delivered straight to your inbox? join the newsletter and get your CSS selector cheat sheet for free You try to be nice to users. Give them visual cues. Maybe you change the border color on a valid input, or show a message when they make a mistake. You think you’re doing a good thing. But then someone opens your form and sees green borders before they’ve even clicked a thing. Valid already? They didn’t even type! It’s wrong. It feels broken. And worse: it actually is misleading. Let’s not even talk about accessibility. Using just colors for feedback? That’s a hard “no” if you care about users with color blindness. CSS pseudo-classes like :valid and :invalid don’t wait for the user to interact. If the input field meets the required rules on page load (or fails them), the styles apply instantly. That’s why your untouched email field might already look like a success story. Not cool. Say hello to :user-valid and :user-invalid. These two pseudo-classes work exactly how you always wanted :valid and :invalid to behave: *They wait for user interaction. Nothing changes until the user actually types, blurs, or otherwise engages with the input. Now that’s user-friendly feedback. If you’re still using :valid/:invalid on untouched fields, you're frustrating users. They’re seeing red borders before they’ve even typed anything. Or worse—green borders that falsely imply their input is good. By switching to :user-valid and :user-invalid, your forms become: ... Read the full article here  ( 4 min )

Problem 1 Longest Substring Without Repeating Characters Problem: You must write an algorithm that runs in O(n) time. Link to problem: https://leetcode.com/problems/longest-consecutive-sequence/description/ Approach: First Thought: Used a basic count[256] array to track frequency of characters. Tried checking frequency and updating start directly if a duplicate was found. Misplaced order of start++ and count[s[start]]--, which caused logic errors for overlapping characters. Final Approach: Used Sliding Window technique with two pointers start and end. Maintained a count array to track how many times a character appeared in the current window. On detecting a duplicate character (count[s[end]] > 1), shrunk the window using a while loop. Then decreased count[s[start]] and moved start forwar…  ( 5 min )

Introduction The Single Responsibility Principle (SRP) is the “S” in the SOLID principles of object-oriented design. It’s often mentioned, sometimes misunderstood, and rarely applied correctly in large Java applications. Definition: A class should have only one reason to change. In practice, this means a class should encapsulate a single, well-defined responsibility — not “one method” or “one functionality,” but one axis of change. In this article, we'll go beyond trivial examples and explore real-world SRP violations, how to spot them, and how to refactor for maintainability and testability. Consider the following UserService class: public class UserService { public void register(String email, String password) { if (!email.contains("@")) { throw new IllegalArgum…  ( 5 min )

By Alireza Minagar, MD, MBA, MS software engineer As a software engineer, I’ve spent most of my time making things work — efficient algorithms, robust logic, clean architecture. But recently, I gave equal attention to how software feels. Enter: SecureFleet, a desktop vehicle monitoring and management tool I’m building with Java Swing. At first, it was utilitarian — basic panels, a static table, and a couple of buttons. But I realized that professional software demands more than just working code — it deserves thoughtful, responsive, and intuitive interfaces. 🔨 What I’ve Implemented: A scrollable JTable with real-world vehicle tracking columns (Plate, Make, Model, Year, Owner, Status). A dedicated alert button (New Alert) highlighted in red for emphasis. A trio of functional buttons below: Track Vehicle, Add Entry, and Admin Panel. Clear color contrast and alignment for visual clarity. 🧠 What I Learned Along the Way: Grouping components into logical panels simplifies both alignment and code readability. GUI building tools (like NetBeans Designer) can help — but manual refinement makes the difference. 🌟 Why This Matters: 💡 What's Next: 🗣️ Let’s Talk: How do you balance aesthetics with functionality in desktop development?

Why I Switched from HashiCorp LRU to Ristretto for High-Performance Caching in Go While working on Buckt, I implemented a caching layer to speed up repeated file reads and downloads. I started with HashiCorp's lru, which was simple and easy to integrate. But as the system scaled and concurrency increased, it became clear that it couldn't keep up. This post highlights the issues I encountered and why Ristretto ended up being a much better fit. While the lru package is solid and predictable, I ran into a few limitations: Blocking Writes - All Add() operations lock the cache, leading to bottlenecks under concurrent load. Fixed Capacity, Not Cost-Based - It evicts based on item count, not memory usage — inefficient when storing large items like files. No Native Metrics - Hit/miss tracking mu…  ( 4 min )

Throughout the first, second, and third articles, we have embarked on a fascinating journey together: from our initial introduction to Observables, where we grasped the fundamentals of the reactive approach, through mastering operators that enabled us to efficiently transform and filter data, to combining streams, which unlocked the ability to synchronize data from multiple sources. We gradually transformed RxJS from an intriguing tool for experimentation into a powerful instrument for real-world tasks. Now, having taken three confident steps, it is time to confront the dark side of reactive programming. Like any technology, RxJS has its pitfalls. One of the most insidious is unclosed subscriptions, which can lead to severe issues such as memory leaks, performance degradation, and even app…  ( 10 min )

In the fast-growing fields of machine learning (ML) and artificial intelligence (AI), image annotation is fundamental to developing reliable models. That’s where image annotation comes in—the process of labeling and highlighting objects, features, patterns, or any other elements of an image that may be useful for a machine learning program or model. However, performing image annotation in-house can also be time-consuming, resource-intensive, and expensive. This is one of the reasons why outsourced image annotation has become a popular approach. In this post, we’ll examine the challenges of standalone image annotation and the best reasons to outsource image annotation for machine learning. 1.

In this video (an excerpt of our next Frontiers of Software Engineering interview), Genaina Rodrigues discusses the critical and evolving role of humans in autonomous and robotic systems, emphasizing the distinction between "Human in the loop" (where humans are directly involved in decision-making and can intervene) and "Human on the loop" (where humans supervise or monitor the system). She argues that humans are an inevitable part of these processes, whether as active or passive stakeholders. She uses several examples to illustrate her points, including challenges in autonomous driving and autonomous avionics. A significant portion of her discussion focuses on the Boeing 737 MAX crashes. She explains that the accident wasn't just a system failure but involved a cascade of issues, includin…  ( 3 min )

Handling async errors in JavaScript often turns into a mess of try-catch blocks everywhere. It clutters your code and gets harder to deal with as the project grows.

When someone shares your website link on WhatsApp, LinkedIn, or Facebook… what shows up? Created by Facebook, OGP defines a set of meta tags that turn any web page into a “social object.” In other words: when someone shares your link, you decide the title, description, image, language, and other details that appear. Without these tags, social networks try to guess what to display—and the result isn’t always pretty.

The Java if-else-if ladder is a fundamental control flow statement widely used in programming to make multiple decisions based on different conditions. It allows developers to execute specific blocks of code depending on which condition evaluates to true, providing a clean and efficient way to handle complex decision-making scenarios. This construct is essential for writing robust Java applications, especially in areas like software development, web applications, and backend services. In practice, the if-else-if ladder helps streamline conditional logic by checking one condition after another until one matches. This approach reduces nested code complexity and improves readability, which is crucial for scalable and maintainable code. It’s often paired with other control structures and modern Java features to optimize performance and user experience in real-time applications.  ( 2 min )

Welcome, my fellow denizens of the cyber realm. If you've ever dared to manipulate a Python list like some medieval peasant, let me introduce you to a tool so blazingly efficient that it makes lists look like dial-up in a fiber-optic world: Queues. We’re running a little duel here—Python’s list.pop(0) versus deque.popleft(). The former? Laughable. It’s the floppy disk of data structures—archaic, slow, and embarrassing in modern computing. Meanwhile, deque? It’s the neural uplink to pure speed. Here’s the showdown: import timeit from collections import deque def list_pop(): lst = list(range(10**5)) while lst: lst.pop(0) def deque_popleft(): dqe = deque(range(10**5)) while dqe: dqe.popleft() if __name__ == '__main__': list_time = timeit.timeit(list_pop, number=1) deque_time = timeit.timeit(deque_popleft, number=1) print(f"List.pop(0) time: {list_time:.6f} seconds") print(f"Deque.popleft() time: {deque_time:.6f} seconds") Operation Execution Time List.pop(0) 1.218925 sec Deque.popleft() 0.006576 sec Read that again. Lists are basically waiting for the apocalypse while queues are flying first class to the future. The list operation is O(n)—which means each time you pop an element, the entire list gets shuffled like some analog relic. Deque, on the other hand, is O(1)—swift, seamless, untouchable. If you’re still using lists where queues would suffice, you’re practically inviting disaster. Imagine hacking the government’s mainframe with code so inefficient it takes a millennium to execute—no, thank you. Upgrade to deque, ascend beyond mortal constraints, and let your programs breathe the sweet air of efficiency. This has been Warlock's Data Structure Command Center—stay frosty out there.  ( 3 min )

⚙️ Why Optimize React Apps? 🧠 The Problem In traditional React setups, all JavaScript code is bundled (using tools like Vite or Webpack) into a few files, often a single large main.js or bundle.js. On initial page load, the browser must download, parse, and execute this entire bundle before the application becomes interactive. Larger applications lead to larger bundles → slower Time-to-Interactive (TTI) and worse Largest Contentful Paint (LCP). Impact: Slower apps cause user frustration, higher bounce rates, and potentially worse SEO. Significantly reduce the initial JavaScript payload. Improve Time-to-Interactive (TTI), making the app usable faster. Enhance perceived performance and overall user experience, particularly on mobile and slow network connections. Reduce memory c…  ( 5 min )

Let me get straight to it, I used to transfer data from Files.com or any other platform where files were dropped to our cloud buckets using scripts. It was all okay when the file sizes were within a few MBs, but things got painful once they grew into GBs. It started taking a lot more time. To speed things up, I tried running the transfer on a VM, it did get faster, but not faster faster, especially when the size crossed 400+ GB. That’s when I started looking for a better way to connect my GCP/AWS buckets directly with these storage platforms, something that could make the transfer process faster and more reliable.

Good error reporting is crucial in programming languages. Doing it at compile time was easy in ArkScript as we have all the context we need at hand, but since we compile code down to bytecode, which is then run by the virtual machine, we loose a lot of context: the source files, their path, their content, we don't have that anymore! Our runtime errors could only show the VM internal state. This article is about how it all changed. I went to the drawing board, and three solutions presented themselves to me: create a source location table in the bytecode, mapping an instruction to a file and line ; emit special instructions that would be skipped by the VM, and used only when the VM crashed, backtracking to find the nearest SOURCE instruction ; extend the size of instructions to 8 bytes and u…  ( 6 min )

Dear Dev Community, Between classes, late-night coding, and the occasional existential crisis, I realized something: school can be overwhelming. There’s always a deadline, always a distraction, and platforms like WhatsApp or Telegram—while useful—aren’t really designed for focused learning. So instead of just complaining about it, I decided to build something. 🎓 Meet Rucks. 🧠 The Problem I wanted something that understood student life. So I built it. ✨ What is Rucks? Plan their days and assignments Track learning goals Reflect and improve Stay motivated without social media noise It’s simple, focused, and built around real academic pain points. It also integrates MxAnalytica, a small analytics engine I built to help improve the experience based on real usage—not assumptions. 🔧 Tech Stack Backend: Dart Frog + Drift for lightweight local storage Analytics: MxAnalytica (custom engine) No Google services — I wanted to build something privacy-respecting and independent 📦 Why I Built It This Way "Between classes, coffee sips, and the occasional existential crisis." Every design choice was guided by real needs and actual friction points I (and my peers) experience as students. 🔍 What’s Next? I'm also exploring ways to monetize it without compromising the experience. If you’ve built something similar or have thoughts on that, I’d love to hear from you. 🧑‍💻 Call for Feedback & Collab Got ideas? Want to test it out?

Successfully hosted a static portfolio using S3 + CodePipeline, documented the entire flow, fixed initial errors, and gained hands-on AWS experience. "Show your portfolio using S3 and CodePipeline." That's what the interviewer said. And guess what I did? I half-did it — only used S3, completely forgot about CodePipeline. Classic fresher moment. But I didn’t stop there. After some caffeine, chaos, and clicking around AWS documentation like a lost tourist, I figured it out! Hosted my portfolio on Amazon S3 deployment using AWS CodePipeline(if you change in index.html it will sudden showcase)--i think automated i don't know I’ve documented every step and every mistake (yes, including naming my bucket static-website-hosting-swiggy because... panic mode ). Lessons learned: Don’t rush. AWS has enough buttons to confuse the calmest soul. Automate with CodePipeline — it’s not just for big apps. As a fresher, do it right the first time — or document how you almost didn't and fix it. That’s still growth. Full write-up (steps + mistakes + current working solution): https://github.com/devops-methodology/static-website-hosting Big thanks to the interviewer who unintentionally gave me my weekend project.

What is a parallel public chain? The transaction execution of traditional smart contract platforms (such as Ethereum) is serial: one transaction can be executed only after the next one is executed, and even if the transactions do not affect each other, they cannot be processed in parallel. This leads to a very low throughput (TPS). Ethereum has an average of only a dozen TPS, and transaction congestion and gas fees soar during peak hours. Parallel public chains are different. They analyze the dependencies between each transaction and execute independent transactions on multiple computing cores at the same time. In layman’s terms, it is to make the blockchain multi-channel parallel operation like an assembly line, split the tasks into small pieces and process them in parallel, which can gre…  ( 6 min )

This turned out to be a pretty cool concept. While working on my site monitoring app, I had around three or four services like uptime checks, DNS lookups, pinging, and a few others. Since I’m not much of a UI designer, I ended up creating separate files for each service, even though they all shared the same layout. That’s when I discovered Flask’s template inheritance. Instead of repeating the same code over and over, you can create a base layout and reuse it wherever you want. It really helped clean things up and made everything way easier to manage. Here’s how you can set it up. template-inheritance home about contact Then, in your child template, you extend the base and override that block: {% extends "base.html" %} {% block content %} hello world!! {% endblock %} That way, you get the shared layout and can customize parts of the page without repeating your code.  ( 3 min )

🚀 What Are Generics in TypeScript? When developing applications, we often need flexibility while maintaining type safety. TypeScript’s Generics solve this challenge by allowing us to create reusable components that can work with multiple data types. In this guide, we’ll break down generics step by step, ensuring you fully understand how to use them efficiently. Without generics, you would need separate functions for different data types. For example: function returnString(value: string): string { return value; } function returnNumber(value: number): number { return value; } This approach leads to redundant code. Generics solve this problem by creating a single function that works for all types. Generics use a placeholder type, such as , allowing a function to handle various dat…  ( 5 min )

See the commit number pointer by the arrow ? (view it in original article) Yes, that's the git short SHA. Only the first 7 digits amongst the 40. The risk of collision is small enough to identify uniquely each commit.

Languages: Python (favorite), JavaScript (basic) Tools: Flet, Pygame, Scikit-learn, Git Concepts: AI Agents, System Control, ML, OOP I plan to explore: Reinforcement Learning – because what’s better than training an agent to make bad decisions before it learns not to? More work on open-source tools that think (or at least pretend to). 💻 GitHub 🌐 Portfolio 🧠 LinkedIn If you’re into AI, Python, or building tools that bite back — hit follow, drop a comment, or just say hi! “Adaptability and consistency are my strengths.

Adding scroll-based animations to your website used to mean reaching for JavaScript — from scroll event listeners to Intersection Observers or third-party libraries like ScrollMagic or GSAP. But what if you could get the same effect with just pure CSS? Meet the modern magic of CSS: animation-timeline: view(); With this property, you can create scroll-triggered animations without a single line of JavaScript. Smooth. Performant. Declarative. ⸻ 🧠 What Is animation-timeline: view();? The animation-timeline property allows CSS animations to be driven by something other than time. When you use the special value view(), the animation is controlled by the element’s scroll position in the viewport. That means your animation will start and progress based on how far the user has scrolled…  ( 4 min )

1. Project Background & Motivation As modern life accelerates, sleep quality is becoming an increasingly vital part of overall well-being. Leveraging Apple Watch and iPhone health data, we can now detect sleep patterns more accurately and combine them with factors like natural light exposure, hydration, exercise, and AI-powered suggestions to build a closed-loop sleep optimization solution. reCharge is a native SwiftUI app that integrates multiple Apple ecosystem technologies — including HealthKit, CoreLocation, WatchConnectivity, StoreKit, localization, and ChatGPT — to deliver a full-featured sleep management experience.

If you’re using Cursor and keep seeing this error: “Connection failed. If the problem persists, please check your internet connection or VPN” You’re not alone. This issue tends to appear randomly—even when your internet is working just fine. It can interrupt your flow and make the experience frustratingly unstable. Cursor uses the HTTP/2 protocol to power many of its AI features, since it allows streaming responses. However, not all networks handle HTTP/2 properly. If you're on a corporate network, using a VPN, or behind a proxy like Zscaler, HTTP/2 connections might fail. As a result, Cursor may struggle to index your code or connect to its AI backend—leading to that annoying “Connection failed” message. Thankfully, there’s a simple workaround. Cursor now includes a fallback to HTTP/1.1, which is slower but much more reliable on certain networks. Here’s how to enable it: Open Cursor Settings (Cmd or Ctrl + ,) Go to VS Code Settings Search for http2 Find and check the option “Disable HTTP/2” This forces Cursor to use HTTP/1.1 instead, which should fix the connection issue and restore access to AI features. ✅ Once you do this, the error should stop showing up and things will run more smoothly.

Amazon Sellers: Navigating the Tariff Disruption Landed costs on China-sourced SKUs have surged by 30–50%, compressing already razor-thin contribution margins. Raise prices, and you lose to the competition and tank conversion. Hold prices, and you bleed cash on every sale. Inventory caught mid-transit racks up storage fees at 3PLs. New suppliers from Vietnam, Mexico, or the U.S. bring delays, compliance challenges, and no keyword history — right when your ad budget is already stretched thin. Margins, inventory flow, catalog continuity, advertising efficiency, brand equity — all under siege. But while others flounder, sellers using Flowin.AI, a comprehensive Amazon listing software, are flipping tariff turbulence into a controlled, profit-driven flywheel by leveraging AI Amazon listing opti…  ( 6 min )

Understanding the Basics of Machine Learning with Python Machine learning (ML) is revolutionizing industries, from healthcare to finance, by enabling computers to learn from data and make intelligent decisions. If you're new to this field, Python is the perfect language to start with due to its simplicity and powerful libraries. In this guide, we'll break down the fundamentals of machine learning, explore key concepts, and provide practical Python examples to get you started. What is Machine Learning? Machine learning is a subset of artificial intelligence (AI) that focuses on building systems capable of learning from data without explicit programming. Instead of writing rigid rules, ML algorithms identify patterns and make predictions or decisions based on input data. There are three main…  ( 4 min )

If you're using an SSD — and let’s be honest, you probably are — you might have come across a spec labeled TBW, or Terabytes Written. But what does it actually mean for the real-world lifespan of your drive? Let’s break it down in simple terms. TBW stands for Terabytes Written, and it’s a metric that tells you how much data can be written to an SSD before the drive is likely to start wearing out. Think of it like a fuel limit — not for how long the drive will exist, but for how much write work it can handle over its lifetime. For example, if your SSD has a TBW of 600, that means you can write 600 terabytes of data to it before you start entering the "wear-out" zone, as defined by the manufacturer. Let’s do a quick, real-world calculation. Say you're a regular user writing about 100 GB per day — downloading files, installing apps, updating your system, working on projects. That’s quite a bit for a typical user, but let’s go with it. 100 GB/day = 36.5 TB/year 600 TBW / 36.5 TB/year ≈ 16 years Yes, sixteen years of daily 100GB writing. That’s how much endurance a 600TBW SSD gives you. And if you write less than that (which most people do), it’ll last even longer. You can monitor your SSD’s health and total data written using tools like: CrystalDiskInfo (Windows) smartctl from smartmontools (Linux/macOS) These tools can show you how much data has been written so far, so you can get a real-time sense of your drive’s life expectancy. TBW is an important but often misunderstood metric. SSDs don’t just suddenly die after hitting the limit, but the risk of data loss increases as the flash memory wears out. That said, for most users — even power users — modern SSDs offer years of reliable performance. So the next time you see a TBW rating, don’t panic. Unless you're stress-testing your drive daily, you're probably fine for a decade or more.  ( 3 min )

In a world overflowing with digital tools, it’s easy to dismiss mental math as outdated — a quaint relic from the pre-calculator age. But there’s something uniquely powerful about sharpening your ability to think numerically without external support. Like optimizing code for runtime efficiency, refining your mental math streamlines your internal thought processes and reduces your cognitive load. This article is based on a short guide I wrote called Multiplying and Dividing Fast - Essential Tactics to Speed Up Mental Calculations with Whole Numbers, the second in a three-part series I began in 2018. The project started as a personal challenge: to improve how I processed numbers mentally. I wanted to go beyond fuzzy estimations and reclaim the skill of clear, structured calculation — the kin…  ( 7 min )

Wait, you can build modal windows without JavaScript? Yep, that's CSS secretly laughing at JavaScript behind its back. At Lingo.dev, we love diving into weird engineering rabbit holes that make other devs do a double-take. Most developers wouldn't even think twice before reaching for a JavaScript library when they need a modal. But what if I told you there's this bizarre, oddball alternative hiding in plain sight? Pure CSS can pull off some surprisingly sneaky tricks that'll make you question everything you thought you knew about frontend development. In this tutorial, we'll explore how to create fully functional modal windows using nothing but HTML and CSS. You can use it for fun, or in production.

The Portable Document Format (PDF), formalized as ISO 32000, has been the global workhorse for digital documents since the 1990s. It was a revolutionary answer to the chaos of inconsistent document rendering across platforms, ensuring that every reader would see the same layout, regardless of software or hardware. From government agencies and hospitals to enterprise back offices and freelance contracts, PDF has become a trusted container of visual fidelity and permanence. But here’s the challenge: the modern digital world doesn’t run on permanence alone. It runs on interactivity, data-driven workflows, responsive design, and seamless integration.

I got this letter from Mosh Hamedani and I just wanted to share it here in case anyone hasn't read it yet. You’ve probably seen the news: Microsoft just laid off 6,000 people. And right away, the internet did what it always does: freaked out. “AI is replacing developers!” But let’s slow down for a second. First off, Big tech layoffs aren’t new. In fact, they’ve been happening for years, long before anyone was worried about ChatGPT. Here are a few examples from the past: 2014: Microsoft laid off 18,000 people after acquiring Nokia 2015: HP cut 30,000 jobs during restructuring 2016: Intel laid off 12,000 employees to shift toward data centers IBM, Yahoo, and others have done the same, multiple times These things happen, not because developers are being replaced by AI, but because companies s…  ( 3 min )

And then they switch from having to be massive consumers of data to extremely massive broadcasters of data. So that means that they need huge amounts of resources both on ingress an…

Moody's credit rating agency downgraded the credit rating of the United States government from Aaa to Aa1, citing the rising national debt as the primary driver behind the reduction in creditworthiness. According to the May 16 announcement from the rating agency, US lawmakers have failed to stem annual deficits or reduce spending over the years, leading to a growing national debt. The rating agency wrote: "We do not believe that material multi-year reductions in mandatory spending and deficits will result from the current fiscal proposals under consideration. Over the next decade, we expect larger deficits as entitlement spending rises while government revenue remains broadly flat." The credit downgrade is only one degree out of the 21-notch rating scale used by the company to assess the c…

Opinion by: Merlin Egalite, co-founder at Morpho Labs Fintechs in the front, decentralized finance (DeFi) in the back: the DeFi Mullet. Today’s fintech companies offer excellent user experiences but are constrained by traditional financial infrastructure — siloed, slow, expensive and inflexible. Meanwhile, DeFi provides lightning-fast, cost-effective, interoperable infrastructure but lacks mainstream accessibility. The solution? Combine fintech’s distribution and user experience with DeFi’s efficient back end. The mullet is inevitable Fintech companies heavily rely on traditional financial (TradFi) infrastructure that is siloed, slow to deploy and run, and costly to maintain. This inefficiency limits their control over costs and product offerings and has potential infrastructure risks. Fin…

Bitcoin’s next explosive move could send the asset to $250,000 by the end of 2025, according to Scott Melker, a crypto analyst and host of The Wolf of All Streets podcast. Speaking in a recent interview, Melker cited growing institutional interest and diminishing volatility as key factors that could drive the next leg up. “250K this year, totally possible,” Melker said, adding that Bitcoin (BTC)’s volatility has declined significantly in recent years. “It used to be about three times as volatile as the S&P. Now it’s less than two times.” He pointed to increased involvement from pension funds and ETF issuers as evidence of a more mature, stable market. The shift, he argued, reflects a broader trend of institutional adoption. “The more institutional money, the more Wall Street money, the mor…

The US Securities and Exchange Commission (SEC) has held discussions with Everstake, one of the largest non-custodial staking providers globally, to explore clearer regulatory definitions around staking in blockchain networks. The meeting, which also involved the SEC’s Crypto Task Force, comes at a time when over $193 billion in digital assets are staked across major proof-of-stake (PoS) networks. However, despite the massive scale of participation, staking remains in a legal gray zone in the US as regulators wrestle with its classification under existing securities law. The previous SEC administration also took enforcement actions against major players such as Kraken, Coinbase, and Consensys due to their staking services. The agency, under pro-crypto President Donald Trump, has recently d…

A man from Wellington, the capital city of New Zealand, has been arrested in connection with an FBI-led investigation into a global cryptocurrency fraud operation that allegedly stole $450 million New Zealand dollars ($265 million). According to New Zealand Police, the man is one of 13 individuals charged after authorities executed search warrants across Auckland, Wellington, and California over the past three days. The charges stem from allegations that members of an organized criminal group manipulated seven victims to obtain large amounts of cryptocurrency, which was then laundered through multiple platforms between March and August 2024. The US Department of Justice has indicted the man under federal law, including charges of racketeering, conspiracy to commit wire fraud, and conspirac…

Paraguayan law enforcement has deported three individuals and arrested another for attempting to steal crypto miners at a facility near the country’s Itaipu hydroelectric dam. According to a May 15 statement from Paraguayan prosecutor Irene Rolón, the men were caught by police soon after breaking into a locked section of Teratech SA’s facility in Coronel Bogado, leading to their arrest. Prosecutors believe the men may have had ties to Teratech as independent contractors, but are still waiting on official confirmation from the company’s CEO. The three deported were Chinese nationals Jinping Duan, Tian Jianyun and Zheng Guanglong, who did not have official entry records into the country.

On-chain data suggests the current profit taking is too weak to extinguish Bitcoin’s current price momentum. Bitcoin (BTC) price has spent the bulk of the week pinned below $104,000 to $105,000, which many analysts have labelled as a resistance zone, but an alternative view suggests that BTC is simply consolidating within a bull flag. A bull flag is a continuation pattern that is characterized by a period of sideways price action following a sharp uptrend, and when the structure confirms or breaks from the trendline resistance, the uptrend continues.  BTC/USDT 1-day chart.

Engineering is more than formulas, projects, or classroom lectures. While academic learning builds a foundation, real-world experience shapes your mindset, communication, and decision-making abilities. From my own journey, I’ve seen how industrial training, leadership roles, and volunteering helped me grow far beyond the textbook. When you work in a real production environment, like a garment factory, you begin to understand how things actually work on the floor. Industrial training teaches you about time management, coordination, and how teams solve problems in real-time. You observe how small improvements in workflow or communication can bring large results. This kind of learning is something no classroom can fully teach. Leadership roles in university also help in developing essential soft skills. Organizing events, managing volunteers, and communicating under pressure make you more confident and responsible. It teaches you how to plan, lead, and adapt — which are valuable qualities in both academic and professional life. Volunteering adds another layer to your development. It allows you to give back to your community while also learning empathy, teamwork, and people skills. Volunteering shows that you are proactive and socially responsible, which employers and organizations appreciate. These experiences make your resume stronger, but more importantly, they shape your personality. They prepare you for interviews, teamwork, and real challenges in your career. You learn how to think practically, solve problems, and communicate your ideas clearly — all of which are essential in today’s job market. If you are an engineering student, try to step outside your comfort zone. Look for internships, attend workshops, join a leadership program, or take part in a volunteering activity. The real world is the best teacher, and the lessons you learn there will stay with you forever. Start early, stay curious, and take every opportunity to grow.  ( 3 min )

Hey there, fellow developer! 👋 Let’s talk about something we all say we love but secretly dread: testing. You know the drill—you push code, cross your fingers, and pray the CI/CD pipeline doesn’t light up like a Christmas tree. But what if I told you testing doesn’t have to feel like a chore? In this guide, we’ll break down the three pillars of CI/CD testing—unit tests, E2E tests, and code coverage—and share practical strategies to make your pipelines faster, safer, and actually enjoyable. Let’s dive in! 1. Unit Tests: The First Line of Defense What they do: Test individual functions, classes, or modules in isolation. Why they matter: Catch bugs early, like checking each ingredient before baking a cake. Best Practices: Mock dependencies (databases, APIs) to keep tests fast an…  ( 4 min )

We didn’t set out to build a typical database. We built something that works with the Postgres you already use, scales when you need it, and doesn’t require throwing everything out just to keep growing. This is a golden age for databases. There’s distributed systems, cloud-native options, fully managed services, and battle-tested engines like Postgres that keep getting better every year. But despite all that progress, scaling your database is still surprisingly hard. Many teams still build applications with a single-node Postgres backend. It’s how a ton of apps start, and how they stay for as long as possible. And for good reason. Postgres is rock solid, well-loved, and everywhere. It’s mature, feature-rich, and backed by an incredibly active community. But fast forward a bit, and that sin…  ( 4 min )

Yesterday, when I was at the bakery buying some snacks, I overheard a conversation between one attendant with another regarding her Android phone not downloading and installing the ChatGPT app. Curious about the subject, I decided to ask her more regarding her issue, and to talk about it. She explained her smartphone was an older model, using Android 8.0, aka Oreo, and that's probably why the chatgpt android app wasn't downloading and installing on it. We talked a while, and I pondered that while there are a lot of reasons for an app not to work on an older Android OS version, the most relevant of them are the security reasons. So I decided to list eight changes from Android 8.0 (Oreo) to Android 15 (Vanilla Ice Cream), the most impactful and relevant of each major version: Project Treble …  ( 10 min )

Hello, everybody! At Info-Polus, we see the opportunities RWA tokenization presents. Today, let's dive into it! The crypto bull market is not only driving up the large, established cryptocurrencies such as Bitcoin and Ethereum. Memecoins such as Dogecoin (DOGE), Pepe, and Shiba Inu, which have a lower market capitalization and are particularly volatile, have recently attracted great attention with impressive price rallies. By contrast, the increases in real world assets (RWA) have attracted less public attention - although many experts believe this crypto segment has excellent prospects… So what lies in RWA? As the name itself suggests, Real World Assets represent tangible and other assets existing in the “real world” (real estate, exchange-traded commodities, art objects) tokenized for use in the DeFi segment. The growing interest in tokenizing real-world assets stems from the promise of greater transparency, security, and global market reach. Let the numbers speak for themselves: the DeFi industry has boomed over the past few years, peaking at $181.22 billion in total value locked (TVL) on December 2, 2021. According to DefiLlama, RWA is steadily carving out its space in this ecosystem, with a TVL exceeding $8 billion in January 2025. Interested in what the future of RWA holds for us?

During my industrial training, I had the opportunity to explore Lean Manufacturing, a system designed to make production more efficient by eliminating waste and focusing on value creation. I learned about important tools like 5S, which stands for Sort, Set in order, Shine, Standardize, and Sustain. This method helps keep workspaces clean and organized, which is essential for safety and productivity. Another key concept I studied was Kaizen, which means continuous improvement. It emphasizes that small daily changes can lead to significant improvements over time. I also gained practical experience with Just-in-Time inventory management, which ensures materials arrive exactly when needed, reducing storage costs and avoiding overproduction. This training helped me connect the theoretical concepts learned in class with real-world production challenges. I realized that efficiency is not only about speed but also about smart use of resources and people. I saw how teamwork and communication play a vital role on the factory floor. Lean Manufacturing is not just a set of techniques; it is a culture of continuous problem solving and improvement. As an Industrial and Production Engineering graduate, I believe this mindset will guide me in all my future professional endeavors.  ( 3 min )

Hey folks, welcome! Welcome to the first article in my new series: Why Python? Unlike C, Python is widely used—and one big reason is libraries. Python comes with many built-in libraries, and you can import even more depending on what you need. Think of a library as a toolkit that helps you do things faster and easier. A Real-Life Example: Randomness Let’s say I’m playing a card game with friends. I never know which card I’ll get next—why? Because it’s shuffled. It’s random! In Python, we can use something similar: import random as rand Just like shuffling cards gives you unpredictable results, the random library in Python helps you generate random numbers or make random choices. In real life, randomness is unpredictable. Cool, right? That’s the magic of Python! Introduction to Variables Now let’s talk about variables. Imagine a kitchen shelf with jars: In programming, think of those jars as variables. Each jar (or variable) stores something inside it—just like a variable stores data. Syntax Example: Let’s say we name our jars like this in Python: jar1 = "Sugar" Now, if we want to see what’s inside, we can do: Easy, right? That’s a wrap! In the next article, we’ll look at types of variables and best practices for naming them. Happy coding!

Longest Unequal Adjacent Groups Subsequence II Difficulty: Medium Topics: Array, String, Dynamic Programming You are given a string array words, and an array groups, both arrays having length n. The hamming distance between two strings of equal length is the number of positions at which the corresponding characters are different. You need to select the longest subsequence1 from an array of indices [0, 1, ..., n - 1], such that for the subsequence denoted as [i0, i1, ..., ik-1] having length k, the following holds: For adjacent indices in the subsequence, their corresponding groups are unequal, i.e., groups[ij] != groups[ij+1], for each j where 0 < j + 1 < k. words[ij] and words[ij+1] are equal in length, and the hamming distance between them is 1, where 0 < j + 1 < k, for all indices…  ( 26 min )

It’s been a long time coming, but I’m thrilled to finally share a new developer tool that emerged from my constant need for better CSS property organisation: Old Fashioned CSS Formatter — a professional-grade Visual Studio Code extension designed to fill a very real and long-standing gap in modern front-end development. If you’ve ever used CSSComb in the past, you know how much it helped maintain order in stylesheets. However, a vacuum was left with the project, which is no longer maintained, and this new tool steps in. When CSSComb stopped receiving updates, it left a hole for many developers, including me. It had a simple job: sorting CSS properties meaningfully. But it did it well. With tools like Stylelint and Prettier becoming more prevalent, it seemed like no one focused anymore on …  ( 4 min )

This is the fourth chapter in my blog series about building a Go Testing Module from scratch. If you’re new here, I recommend checking out the previous post for some context. In this post, I’m diving into two new packages I’ve created — goldy and must. These tools tackle problems you’ve probably faced in writing tests, making your test code cleaner, more readable, and a lot more enjoyable to work with. Let me walk you through how I built these packages to solve those familiar testing headaches. goldy Package You’ve likely faced the frustration of testing a function that generates a complex, multi-line string — like a JSON response or a formatted report. Hardcoding that string in your test code turns it into a cluttered mess that’s tough to read and even harder to maintain. I’ve been ther…  ( 6 min )

Understanding cp, mv, and man in RHEL 9 Like a Pro-in-Progress “This needs to be shared. Or saved. Or moved somewhere less... sketchy.” Enter today’s heroic trio: cp, mv, and man.

This post demonstrates a TypeScript pattern I've been experimenting with for the last year or so. I've been calling this pattern "inductive type constraints", but perhaps a better name would be "smart constructors", since they have "correct by construction" semantics (here's a nice article about them). "Smart constructors" definitely sounds cooler, but "inductive types" are what they're called in other typed languages, so I went with that. Before we dig into how they work, here are a few examples of how they can be used to solve a few long-standing TypeScript issues: Exact "exact types" is the 2nd-most popular feature request of all time Exact ensures that a type does not have any extra properties (Playground) Json One of the oldest TypeScript issues (#187) (Playground) In the TypeSc…  ( 4 min )

A Python package named modinit that facilitates the rapid scaffolding of AI model training repositories with a standardized, best-practice structure. This tool is designed to save time and ensure consistency across machine learning projects. In machine learning and AI development, it's common to begin with Jupyter notebooks for experimentation and prototyping. However, as projects mature, there's a need to transition this code into a more structured, maintainable, and deployable format. This transition poses several challenges: Code Organization: Notebooks often contain a mix of data processing, model definition, training loops, and evaluation code, making it hard to modularize and reuse components. Version Control: Tracking changes in notebooks is less straightforward compared to plai…  ( 4 min )

A 'Hero' is a large banner at the top of a website's home page. As it is the first thing a visitor sees when they enter a website, it's the one chance to make a first impression. This can be an image or a video. For our purposes, we'll only need an image. This image should be high-quality and meaningful. A purely decorative image won't do. It should convey the proposition of a fall festival in some capacity. The image shouldn't be too busy either. Negative space is necessary, as the purpose of the central graphic is to complement the other components of the section, not override them. The text block is where you capture interest. It consists of one or both of two parts: The headline delivers the core message in just a few words. Luckily, we already have a very fitting tagline: "Real Farm…  ( 4 min )

Calculus is often taught as a tool for solving problems, such as rates of change, areas under curves, and optimization. But what if it’s also a lens to understand how the world quietly evolves? In coding, every function, loop, and variable tells a story about change—about moving from one state to another, sometimes subtly, sometimes dramatically. The derivative isn’t just a slope; it’s a whisper about the next moment. The integral isn’t just an area; it’s the sum of all moments passed. As a developer and math lover, I find myself drawn to these silent narratives, where math and code meet philosophy. In this space, I’ll explore those intersections: How math powers AI models How quantum ideas challenge our intuitions How elegant code can be more than just efficient — it can be poetic. If you love thinking deeply about the things most take for granted, welcome aboard. Let’s decode change together!!  ( 3 min )

🔙 Previously: What is UDP? Understanding the "Unreliable" Transport Protocol If you’re just starting to learn about computer networks, you might find the term "UDP" a little confusing, especially when people describe it as "unreliable." Don’t worry, In this post, we’ll break things down simply so you can understand what’s happening behind the scenes when a message is sent using UDP. Think of a UDP packet like a shipping box. It contains two things: A very small label (header) – just 8 bytes long The actual content (data) – what you want to send The label has the following four items: Source Port (16 bits): Like the return address, it tells the receiver where the message came from. Destination Port (16 bits): Tells where the message should go - kind of like a delivery address. Len…  ( 5 min )

Have you ever wondered how Node.js handles asynchronous operations so efficiently? The secret lies in the Event Loop, a core component that orchestrates the execution of tasks. In this series, "Node.js Event Loop Visualized," we will dive deep into the inner workings of the Event Loop using a powerful tool: the Event Loop Visualizer. The Event Loop Visualizer is a tool I've been developing, based on a fork of an existing project. It offers a unique insight into the real execution of the Event Loop by utilizing a modified version of the Node.js core. Unlike other tutorials, courses, and posts that often rely on simulations to explain the Event Loop, this tool captures the actual execution, recording each phase in real-time. This provides a clearer and more accurate understanding of how Node.js manages tasks and events. Feel free to explore the Event Loop Visualizer and see it in action for yourself! The Event Loop Visualizer is composed of several key sections: Code Editor: Write and execute JavaScript code to see how it interacts with the Event Loop. Macrotask and Microtask Queues: Visualize how tasks are queued and processed. Call Stack: Observe the current call stack and how functions are executed. Event Loop Phases: Track the different phases of the Event Loop, such as Timers, Poll, and Check. Ticks & Rejections Loop Phases: Understand how Node.js handles next ticks and microtasks. Metrics: Monitor loop counts and event processing statistics. Simulated Terminal: View real-time output from your code execution. In each post of this series, we will analyze a specific block of code and explore how it is executed within the Event Loop. We'll cover a range of examples, from basic like timers to more advanced such as handling sockets and streams. Stay tuned as we embark on this journey to demystify the Node.js Event Loop. Whether you're a seasoned developer or just starting, this series will provide valuable insights and practical knowledge. Let's get started!  ( 3 min )
